I ordered plane tickets and hotel rooms on my Visa Signature XXXX card. We had to cancel XXXX tickets and buy another. That is not the original issue, although it will come up later. I called to pay the updated bill on the XXXX/XXXX/16 even though the billing date on the statement I received was XXXX/XXXX/16. I got the corrected number and was transferred to the payment department. They tried to charged me the amount for the canceled tickets plus interest. After we got the balance corrected, they still tried to insist that we pay interest, even though we were before the bill due date. After arguing for a while, they conceded the interest and we tried to pay the full amount of XXXX. However, my debit card had a limit of XXXX. So we told them we would call back in a day or so to pay the rest of the charges. 

So when we called back on XXXX/XXXX/16 to pay the remaining XXXX. They again tried to charge me for the tickets I had canceled ; we cleared that up, eventually. Then they tried to insist that I owed them interest BECAUSE I had made a partial payment on XXXX/XXXX/16. They wanted {$20.00} in interest from XX/XX/XXXX-XX/XX/XXXX, equaling {$5.00} a day. On top of that, they continued to insist that there might be more charges if I did n't pay the interest that I was disputing. I told them that I would not be paying the extra charge and ended the phone call without finishing my payment of XXXX because they had made me so upset. 

On the statement they sent me, it states clearly that : " We will not charge interest on purchases on the next statement if you pay the new balance total in full by the payment due date, and you had paid in full by the previous payment due date. '' I did not have a previous balance and the due date had not passed. 

I will be trying to pay the undisputed amount again without paying the interest. However, I wanted to make sure someone knew what they were trying to do.
