Amex Credit Card Complaint

Amex Credit card department,

Late fee California

I have been an Amex cardholder for over - years. I have always paid my bill on time and in full. I mailed my last payment on - - for payment due - -. I received my bill and was charged $170.00 in late fees and interest as my payment was received - -. I called Amex and was told there was nothing they could do. I could not figure out how it took - days to go from - to -. They just kept saying they would not do anything to remove the charges. I called again the next day and - told me that I was a valued cardholder but she would do nothing to remove the charges. She told me that I was not a desirable cardholder since I paid my bill in full so they did not make any money off of me. I also have a - Amex so they pay me to use the card in the form of the rebate check. Lastly I was told that I should have considered it was tax season and mailed my payment earlier. So basically it was all my fault and they refused to do anything.
