Yes, banks are legally required to investigate disputed charges, especially unauthorized ones, following specific federal regulations like the Electronic Fund Transfer Act (EFTA) for debit cards, involving a formal process that includes notifying the customer, reviewing transaction details, potentially issuing provisional credit, and working with merchants or networks to resolve the claim within set timeframes (often 10-45 days).

What are the chances of winning a bank dispute?

Chances of winning a bank dispute (chargeback) are generally good for consumers with valid claims, often resulting in provisional credit and a win, but statistics show merchants win less than half their challenges; for consumers, having strong evidence like proof of non-delivery or unauthorized charges is key, while merchants must meticulously follow rules, provide detailed data (proof of delivery, communication), and act quickly to improve their odds, which are much better in "friendly fraud" (around 44%) than true fraud (around 9%). 

How long does it take for a bank to investigate a dispute?

If you file a dispute after receiving your free annual credit report, they have 45 days to investigate. If you submit additional information relevant to your dispute during the 30-day investigation period, they can extend the investigation period for 15 additional days.

What evidence helps win a charge dispute?

To win a charge dispute, provide strong evidence directly refuting the claim, such as proof of delivery/service, transaction details (receipts, AVS/CVV matches), and customer communications (emails, chats) showing agreement or satisfaction, alongside proof the customer accepted your terms of service/policies. Tailoring evidence to the specific dispute reason (e.g., delivery proof for "item not received") is crucial for success.

What is the 15 3 credit card trick?

The 15/3 credit card payment method is a strategy to lower your credit utilization by making two payments during a billing cycle: one about 15 days before the statement closes and another 3 days before the due date, keeping balances low when reported to bureaus, though its effectiveness as a "hack" is debated; the core benefit comes from reducing utilization, not the specific timing. A related but different concept is Buy Now, Pay Later (BNPL) Pay-in-Three, where a purchase is split into three installments (first at purchase, two more monthly). 

What are valid reasons for disputing a charge?
