XXXX American Express credit card payment was due on XXXX XXXX, 2015. I always pay the bill electronically 3 or 4 days in advance. On XXXX XXXX, 2015 I logged in multiple times to authorize payment. The system would not let me put in a payment with a date of earlier than XXXX XXXX, 2015. I assumed this was because of the holiday and went ahead and authorized payment as early as it would let me. Now I get the bill and see that there is a {$25.00} late fee and {$35.00} interest charge on a {$1700.00} balance. I always pay in full ; I never carry a balance. If they did this to me I would assume they treated everyone who logged in on XXXX XXXX to pay their bill the same ( would n't take the payment until after the due date ). I have no other way to pay but electronic -- - I do not get a statement ; everything is on-line. So on XXXX XXXX it was not possible to pay a bill electronically with a due date of XXXX XXXX. This never happened before and I believe it is just not fair.
