In a credit card or debit card account, a dispute is made in which the validity of a transaction has been registered to the account. Customers dispute charges for a variety of reasons, including unauthorized charges , excessive charges, failure to deliver merchandise, dissatisfaction with the product (s) received, or billing errors.
In the United States , in the event of fraud, the cardholder is liable for a maximum of $ 50 worth of fraudulent charges.  Many card issuers will waive this fee.
