A $48 charge on a credit card statement can create two separate jobs. First, identify what happened. Then create a written record before the deadline passes. A call to the number on the back of the card can get the conversation started, but a phone call by itself does not preserve the federal billing-error rights described by the Consumer Financial Protection Bureau, or CFPB. The formal step is a written billing error notice.
Act I: Put the dispute on the record
Why a call is only the first step
Calling promptly makes sense when a charge is unfamiliar, a payment is missing, or the amount looks wrong. A representative may recognize a merchant name, explain a pending charge, or open a case. Still, the CFPB says that a consumer must also send a written notice to protect rights under the billing-error rules. Those rules are set out in Regulation Z's billing error resolution section.
Think of the call as a quick fact check and the letter as the document that marks the dispute. Keep a copy of the letter, the relevant statement, and notes from every follow-up call. A simple record can include the date, time, representative's name, and a short summary of what was said. That file is useful if the explanation changes later or a response does not arrive when expected.
Count from the first statement showing the problem
The written notice generally must be sent within 60 days after the statement on which the error first appeared. CFPB materials describe the timing as 60 calendar days after the charge appeared on the statement, or, for a missing payment issue, within 60 days of receiving the statement that should have shown the payment. When dates are close, counting from the earliest statement that shows the issue avoids relying on a later date.
The notice goes to the billing-dispute address printed on the statement, not necessarily the address used to mail a payment. The CFPB's billing-error guidance says to include the account holder's name and address, account number, the amount in question, and a clear explanation of what appears to be wrong and why.
- Pull the statement where the charge or missing payment first appears.
- Find the address specifically listed for billing errors or disputes.
- Write the account details, disputed dollar amount, and a plain description of the problem.
- Save a copy of the notice and note the date it was sent.

Act II: Keep the rest of the account current
What can happen during the investigation
After receiving a written dispute, the card company generally has 30 days to acknowledge it in writing, unless it has already completed the required resolution steps within that period. The acknowledgment is not the final decision. It is confirmation that the company received the notice. Keeping that response with the original letter can help establish the timeline.
While the investigation is open, federal guidance says the disputed amount, related finance or other charges, and interest on that disputed amount do not have to be paid. A consumer also should not lose a purchase grace period because of the disputed amount. The rest of the bill does not disappear, though. The undisputed portion remains due under the account agreement.
For example, if a $900 statement includes one disputed $48 charge, the billing dispute does not automatically excuse the other $852. Paying or not paying any amount can have consequences under an account agreement, so the statement's instructions remain important. A charge can also be disputed after it has been paid, although a credit or refund would generally wait until the company finds in the consumer's favor.
Check statements before a small error becomes a deadline problem
A monthly statement review is the lowest-cost place to catch a problem. Compare the opening balance with the prior statement, scan new purchases, and look for unfamiliar merchant names or optional fee-based add-on products. Some charges are legitimate but appear under a parent company or payment processor name. Others may need a closer look.
For an unauthorized-charge question, the card agreement is a useful starting point because it explains the account's procedures. The CFPB also notes that consumers can look for agreements through its credit card dispute guidance. Account rules do not replace the written-notice deadline, so it helps to handle both tasks at the same time: review the agreement and prepare the written notice.
Read the final answer, not just the account balance
If the company decides the bill was wrong, it must remove the charge or credit the payment. The correction should show up on a later statement, which makes the next statement worth reviewing even after a favorable answer arrives.
If the company decides the bill was correct, it must explain the reason in writing, state the amount owed, and provide a payment due date. That written explanation matters because it identifies the basis for the decision. The CFPB describes these resolution duties in its guidance on a payment that does not show on a statement as well as its broader billing-error materials.
Purchase problems may start with the seller
Some billing errors involve a purchase rather than an unfamiliar transaction. Federal guidance includes charges for goods or services that were not received or were not accepted on delivery. The 60-day written-notice timing still applies when the charge appears on the statement.
In a purchase dispute, contacting the seller first and asking for a refund or reversal can establish what happened. If that does not resolve the issue, a card-company dispute may be available. This is often called a chargeback, meaning a request to reverse a card transaction. The CFPB notes that the result depends on the facts and the card's rules, and defective goods or services can involve a different process.
There are also limited circumstances in which a consumer may assert claims or defenses related to a purchase against the card company. The available CFPB material says this generally involves a good-faith effort to resolve the matter with the seller and a purchase made in the consumer's home state or within 100 miles of home. The source text does not provide the complete list of conditions, so those facts alone do not settle an individual case. See the CFPB's overview of refunds for card purchases for the agency's explanation.
Where the official guidance leaves open questions
The public sources are clear about the 60-day notice window, the 30-day acknowledgment rule, and the treatment of the disputed amount while a case is pending. They do not state a single final-decision deadline after acknowledgment. They also do not explain in detail how interest may be handled if a dispute is decided against the consumer, beyond the pending-dispute protections.
The reviewed materials also do not cover every possible next step if a company does not respond, state-law differences, or possible effects on credit reports and scores. For additional consumer reading, the Federal Trade Commission maintains pages on using credit cards and disputing charges and a sample dispute letter. The practical core remains simple: review the statement, call to clarify if needed, send the written notice to the correct address within the deadline, and keep the paperwork together.
