<prompt> Human: She has to be lying to him. My dad pays his card off every month so he doesnt understand that 25 interest is per year, not per month. Ill pay it so that she, or someone else isnt scamming him for another month. But because hes in jail theres no way for him to contact the credit card company and put a hold on his card. I dont want to pay it just to have someone use the card with out his authorization. Any suggestions would be appreciated.  <response>: How long has the debt been sitting to have interest charges? Even if its been sitting for 2 months 2 cycles of interest charges while hes been in jail, there is no way the interest is 600 on 2,500 at a 25 interest rate. It would be more like 60.Edit: From your comments and update, Id honestly just let this go. This is his debt, not yours. If hes only in jail for 2 months, then let him figure out how to pay it when hes out. I understand you want to help your dad out, but its not your responsibility to do all the legwork to try and pay his bill while also deal with people trying to steal from you. Hes only going to accumulate like 100ish in interest at most during this time. This approach avoids you handing money over to untrustworthy people and freeing up credit on the card for these people to turn around and spend assuming hes close to his max.
