If you opened your statement and saw a line that reads “Cusi Cusi” and you don’t recognize it, you’re not alone — unfamiliar billing descriptors cause a lot of worry. This guide walks U.S. consumers through practical verification steps, explains how billing descriptors work, and shows exactly how to dispute a suspicious or unauthorized credit card charge.
“Limited public information is available for Cusi Cusi as of 2025. Consumers should verify details directly with their bank or the merchant.”
Quick overview: Why unfamiliar charges happen
An unfamiliar credit card charge like Cusi Cusi can come from several normal or problematic sources:
- A subscription or recurring service you forgot about (trial that rolled into a paid plan).
- A third-party or affiliate billing name that looks different from the brand you know.
- A merchant using a parent company / payment processor that appears under a different descriptor.
- A mistaken or unauthorized charge (fraud or misuse).
Many merchants appear under short billing descriptors on statements that don’t match the storefront name you expect — that’s a common cause of confusion.
Step 1 — Don’t panic: verify before you dispute
Before you start a formal dispute, do these quick checks:
- Check date + amount — Match the transaction date and amount with recent purchases.
- Ask household members — Sometimes spouses, roommates, or children authorized a purchase.
- Search your email — Look for order confirmations, receipts, or subscription notices around that date.
- Google the billing descriptor (exact spelling) — Try searches for variations:
Cusi Cusi
,CusiCusi
, orCUSI
. Note: there are companies named CUSI (Continental Utility Solutions) that appear online, but that is not proof that a “Cusi Cusi” charge on your account is legitimate; always verify with your bank or the merchant.
Step 2 — Try contacting the merchant (when possible)
If you can identify contact info from a receipt, confirmation email, or by searching the billing descriptor:
- Call or email the merchant and ask for:
- The full merchant name, website, and phone number they used to bill you.
- The original order or subscription ID.
- How to get a refund or cancel recurring billing.
If you can’t find merchant contact info, move to Step 3.
Step 3 — Contact your card issuer immediately
If merchant contact fails or you suspect fraud:
- Call the number on the back of your card and report the unfamiliar charge.
- Ask the issuer to investigate and to temporarily block further charges if needed. The issuer can often flag the merchant and may issue a provisional credit while they investigate. The Consumer Financial Protection Bureau recommends contacting the card company as your first step.
Step 4 — Know your legal rights (Fair Credit Billing Act)
Under U.S. law (the Fair Credit Billing Act), you have protections when disputing certain billing errors, including unauthorized charges. Important points:
- You generally must dispute the charge within 60 days from the date the issuer mailed (or made available) the billing statement that shows the error.
- Follow your issuer’s instructions; many ask that you call first and then follow up in writing. Keep copies of all communications.
Chargeback vs. refund — what’s the difference?
- Refund: A merchant agrees to return the money (best when the merchant is responsive).
- Chargeback: A formal reversal initiated through your card network via the issuer when you dispute the charge. Chargebacks are governed by card rules and can take weeks; they’re not the same as a merchant refund.
Step-by-step: How to dispute a Cusi Cusi charge (practical checklist)
- Gather evidence: statement screenshot, emails, order numbers, any communication.
- Call the merchant (if contact info exists). Record date/time and representative name.
- Call your card issuer (number on back of card). Explain it’s an unknown/unauthorized charge.
- Follow up in writing if your issuer asks (keep copies). Use certified mail or secure message when possible. The FTC and CFPB have sample letters and templates you can adapt.
- Ask for provisional credit while the issuer investigates. Many issuers will temporarily remove the charge from your balance.
- Monitor account & follow up until resolved. Keep records of each step.
Preventive tips (how to avoid future surprises)
- Use virtual or disposable card numbers for online purchases and subscriptions; they mask your real card number and can be single-use. Many issuers and services explain how virtual cards protect payments.
- Enable transaction alerts (text/email) for every charge.
- Review statements monthly and set calendar reminders to check accounts.
- Don’t save card details on unfamiliar websites.
- Use strong, unique passwords and enable two-factor authentication on merchant accounts.
Merchant verification tips (how to judge a billing descriptor)
- Look for a website and domain that matches the company name in the descriptor.
- Check WHOIS or business registration info for the merchant if you’re suspicious.
- If a merchant uses a third-party payment processor, the descriptor may show the processor’s name instead of the storefront. In that case, the merchant should provide the full merchant name upon request.
When to escalate: file a complaint
If the issuer does not resolve your dispute or you see signs of identity theft:
- File a complaint with the Consumer Financial Protection Bureau (CFPB) or the Federal Trade Commission (FTC). CFPB and FTC pages explain next steps and how to submit documentation.
- Consider placing a fraud alert or credit freeze with the major credit bureaus if you suspect identity theft.
FAQ — Quick answers (5–6 questions)
Q1: Will disputing a charge hurt my credit?
A: No — telling your card issuer you’re disputing a charge is a consumer right. The issuer may mark the amount as “in dispute” but should not report you negatively for the disputed amount while it’s under investigation.
Q2: How long do disputes take?
A: Timeframes vary. The issuer must acknowledge receipt quickly and investigate; card network chargebacks can take several weeks to months depending on complexity.
Q3: Can I get my money back right away?
A: Some issuers offer a provisional credit during investigation. If the issuer finds the charge was unauthorized or incorrect, you’ll keep the credit; otherwise it may be reversed.
Q4: What if I can’t find any information about Cusi Cusi online?
A: That can happen. “Limited public information is available for Cusi Cusi as of 2025. Consumers should verify details directly with their bank or the merchant.” If no merchant contact exists, escalate to your issuer and file a complaint if needed.
Q5: Should I file a police report?
A: File a police report if you suspect identity theft or large fraudulent activity. Your issuer and the credit bureaus may also request a police report in certain cases.
Q6: Can I use a virtual card for subscriptions?
A: Yes, many virtual card services can create a card tied to your account that you can limit or cancel — a strong way to stop unwanted recurring charges. Check issuer availability and terms.
Final tips & takeaways

- Follow the practical checklist: verify purchases, contact the merchant, contact your issuer, and use your rights under the Fair Credit Billing Act if needed.
- Use virtual cards, alerts, and monthly statement reviews to reduce the chance of future surprises.
