When a charge on your credit card looks wrong, most people call the store, get nowhere, and give up. They assume the money is gone and the bank will side with the merchant. That belief costs regular people real money every year. There is a federal law built for this exact moment, and it has been on the books since 1974. It is called the Fair Credit Billing Act, and it gives you the right to dispute a charge in writing. The catch is that almost no one explains how it works before you need it.
The Fair Credit Billing Act applies to credit cards and other open lines of credit. It covers billing errors, and that term is broader than most people think. A charge for something you never bought counts. A charge for the wrong amount counts. A charge for goods that never arrived counts. Math mistakes, double charges, and fees you did not agree to all count as well. If you were billed for a hotel night you canceled or a subscription you stopped, that is a billing error too.
The most important part is the clock, and this is where people lose their rights without knowing it. You have to send a written dispute within 60 days of the date the first statement with the error was mailed to you. Not 60 days from the purchase. Sixty days from the statement. A phone call feels easier, but a call does not protect you the same way a letter does. Send the dispute to the address the card issuer lists for billing questions, not the address you use to mail payments. Keep a copy of what you send and proof of the date.
Once your letter arrives, the law puts the burden on the bank, not on you. The issuer has to acknowledge your dispute within 30 days. It then has two billing cycles, and no more than 90 days, to either fix the error or explain in writing why the charge stands. While the investigation runs, you do not have to pay the disputed amount, and you do not owe interest on it. The bank cannot report that amount as late to the credit bureaus during this window. It also cannot close your account just because you spoke up.
There is a second right that trips people up because it works differently. If you buy something and the product or service turns out to be defective or not as described, you can withhold payment even when there was no billing mistake. The law sets two conditions on paper. The purchase has to be more than 50 dollars, and it has to happen in your home state or within 100 miles of your address. Many card issuers quietly waive both limits, so it is worth asking even if your purchase falls outside them. You also have to make a real effort to fix the problem with the seller first.
People use the word chargeback for all of this, but a chargeback is not the same as the federal law. A chargeback is the private process the card networks like Visa and Mastercard run to pull money back from a merchant. The Fair Credit Billing Act is the law that gives you rights the bank has to honor. In practice your dispute often triggers a chargeback behind the scenes, but the law is what protects you if the bank drags its feet. Knowing the difference helps because you can point to the statute when an agent tells you nothing can be done. That single fact changes how the call goes.
Here is the part that catches families off guard. Debit cards do not get the same protection, because the money leaves your account right away. Debit disputes fall under a different rule called the Electronic Fund Transfer Act. Your losses can be capped at 50 dollars if you report a problem fast, but that cap climbs to 500 dollars if you wait more than two business days. Wait past 60 days and you can be on the hook for everything. This is one reason many people put recurring bills and big online orders on a credit card instead of a debit card.
The lesson is simple and worth repeating to anyone you care about. When a charge is wrong, do not just call and hope. Read your statements every month so the 60-day clock never runs out on you. Put your dispute in writing, keep records, and name the law if you have to. You are not asking the bank for a favor, you are using a protection that Congress wrote for you. The people who know this get their money back, and the people who do not usually eat the loss. Now you are in the first group.
