Answers about Credit Card Disputes
Can the bank apply late fees and interest while my billing dispute is being investigated?
Generally, if you have filed a proper billing dispute with the bank, you would not need to pay—and the bank cannot try to collect—any portion of any required payment that you believe is related to the disputed amount while the dispute is being investigated. This includes related finance or other charges.
However, the bank can act to collect any undisputed portion of the item or bill.
