KOS Booster Charge on Credit Card [Identified]
A KOS Booster charge on credit card can feel confusing if you don’t recall signing up for anything. Unfamiliar charges are often legitimate purchases or subscriptions that simply use an unclear merchant name.
This guide walks you through what the charge typically relates to, how to check your records, and practical next steps.
What Is the KOS Booster Charge on Credit Card?
The KOS Booster charge on credit card is a billing descriptor that may appear on statements from credit cards, debit cards, or bank accounts.
The exact merchant behind “KOS BOOSTER,” “KOS*BOOSTER,” or similar wording has not been confirmed through a current official billing source.
Two common possibilities surface in public information. One involves a digital or in-app purchase, such as a game booster pack, upgrade, virtual currency, or premium access.
Historical material references a mobile title called KOS Trading Card Game (also known as Keepers of the Sin), a strategy card game available on iOS and Android that featured booster packs.
That historical link does not prove any current charge belongs to that game. No active official store listing or billing page currently ties the descriptor to it.
The other possibility is a purchase or subscription from KOS, a plant-based nutrition brand at kos.com. The company sells organic protein powders, superfood blends, and related products.
Some energy-related items use flavor names like Boostberry. KOS offers recurring Subscribe & Save deliveries every 30, 60, or 90 days with options to adjust, pause, or cancel.
The brand’s site does not publish an official statement descriptor matching “KOS BOOSTER,” so any connection remains unconfirmed until matched against your order history or receipt.
Statement wording can vary by bank or processor. You might see:
| Common Variation | Notes |
|---|---|
| KOS BOOSTER | Basic form |
| KOS*BOOSTER | Asterisk separator |
| KOS BOOSTER PURCHASE | Added detail |
| KOS BOOSTER GAME | Possible game reference |
| CHECKCARD KOS BOOSTER | Debit-style prefix |
| PENDING KOS BOOSTER | Authorization hold |
Always note the full description, exact amount, date, and any extra details like city or phone number on your statement.
KOS Naturals, LLC (the nutrition company) holds an A+ BBB rating and operates from Santa Barbara, California. It is a legitimate brand with established products and customer service channels.
Evidence linking the specific “KOS BOOSTER” descriptor remains limited, so treat any assignment as provisional until you verify it against your own records.
How to Verify a KOS Booster Charge
Start with the details already on your statement. Write down the full merchant text, amount, transaction date, and posting date.
Next, search your email for receipts or shipping notices containing “KOS,” “kos.com,” “booster,” “Boostberry,” the exact dollar amount, or words like “order,” “subscription,” or “receipt.” Check spam and promotions folders.
Review recent activity on shared devices or accounts. Ask household members if anyone bought a game upgrade, card pack, protein powder, or similar item. Children or family users sometimes make purchases that appear on a parent’s card.
Check app-store histories:
- For Apple: Open Settings or the App Store, go to purchase history, and search by amount or date.
- For Google Play: Review order history in the Google account used on the device.
Look inside any recently played mobile or console games for purchase records, virtual currency balances, or booster inventory. Also log into any kos.com account (if you have one) and compare the charge date and amount against order or subscription history.
If the charge still does not match, contact your card issuer using the number on the back of the card. Request the complete merchant descriptor, legal name, merchant category code, and whether the transaction is marked recurring. Issuers often hold more detail than the shortened statement line.
Pro Tip: Take screenshots of the statement line, any matching receipts, and account order pages before you contact anyone. Clear records speed up verification and any later dispute.
Is the KOS Booster Charge a Subscription?
It may be a one-time purchase or a recurring charge. Game boosters and virtual items are often single transactions. Nutrition orders through KOS can be one-time or set on a Subscribe & Save schedule.
Look for patterns: the same amount appearing monthly or on a fixed cycle, renewal language in an email, or an active entry in Apple or Google subscriptions. KOS subscriptions typically allow easy changes or cancellation through the customer account at kos.com.
Deleting an app does not cancel an underlying subscription; you must cancel through the platform or merchant that billed you.
What to Do If You Do Not Recognize the Charge
Confirm first that the charge has posted rather than sitting as a temporary authorization. Authorizations usually drop off within a few days if unused.
If nothing matches after checking emails, app stores, game accounts, family members, and any kos.com history, treat the charge as potentially unauthorized. Contact your card issuer promptly.
For credit cards, federal rules generally give you strong protection when you report a billing error in writing within 60 days of the statement date. Debit-card rules differ and often require faster reporting.
You can also reach out to the possible merchant once you have matching evidence. For a confirmed KOS nutrition order, the company lists support at hello@kos.com and a phone line at 1-844-586-4567 (Monday–Friday, 9 a.m.–5 p.m. Pacific Time).
Use those contacts only after you have an order number or receipt that lines up with the charge. Do not share full card numbers or passwords with any support contact that reaches out to you unsolicited.
If the charge ties to a game or in-app purchase, use the official refund process for Apple or Google Play, or the game’s own support channel found inside the verified app or account.
Common Mistakes: Assuming the charge is fraud solely because the name is unfamiliar. Many legitimate merchants use short or product-based descriptors. Another frequent error is deleting an app and thinking that cancels billing. Always cancel through the original platform or merchant account.
Steps to Cancel or Dispute
- Gather your statement, any receipts, and screenshots.
- Contact the merchant first if you can identify it and the purchase was recent. Request a refund or cancellation confirmation in writing.
- If the merchant does not resolve it, open a dispute with your card issuer. Provide the documentation you collected.
- Monitor the account for additional charges and consider temporarily locking the card or requesting a replacement if you suspect compromise.
- Change passwords and enable two-factor authentication on any linked game, app, or shopping accounts.
Refund policies vary. Consumed digital items or opened product packages may have limited eligibility. Policies also differ by issuer and by whether the charge was credit or debit.
FAQs About KOS Booster Charge on Credit Card
Q: What is the KOS Booster charge on my credit card?
It may relate to a game booster, virtual item, upgrade, or a purchase or subscription from the KOS nutrition brand. The exact merchant is not confirmed by an official current billing source, so verify against your full statement details, emails, app-store history, and order records.
Q: Is KOS Booster a legitimate company?
KOS (kos.com) is a real plant-based nutrition company with an A+ BBB rating. A historical mobile card game also used the KOS name and sold booster packs. The specific “KOS BOOSTER” descriptor itself lacks an official public confirmation linking it to either source.
Q: How do I cancel a possible KOS subscription?
Log into the relevant account (kos.com for nutrition, or the app-store/game account for digital purchases). Look for subscription or order management options. Cancel there and request written confirmation. Contact the merchant support channel only after matching the charge to a real order.
Q: Should I dispute the KOS Booster charge right away?
First complete the verification steps above. If no legitimate purchase or subscription turns up after checking all records and household users, contact your card issuer promptly and follow their dispute process. Acting within the time limits set by your issuer protects your rights.
Conclusion
A KOS Booster charge on credit card is most often either a digital game-related purchase or a KOS nutrition order or subscription, but the exact source stays unconfirmed without matching evidence from your own records.
Start by reviewing the full statement line, emails, app histories, and any shared accounts. Contact the possible merchant only after confirmation, or work with your card issuer if the charge remains unexplained.
Taking these calm, methodical steps usually clears up the mystery quickly and protects your account.
