Amex Credit Card Complaint

Amex Credit card department,

APR or interest rate Rhode Island

I am writing to request a rebate of the late charges I paid over the - month billing period ended -/-/15 and the 48 % increase in interest charges during this period when my interest rate was increased from 14.24 % to 27.24 %. This caused me to be charged approximately an extra $1000.00 in interest. The late fee charges were $110.00. I was told by both - - and American Express in many telephone calls to wait until after the - payment plan was approved before requesting abatement of these onerous charges. In a call to American Express on -/-/15, I was told that they no longer handle my account and referred me to - -. In a call to - -, I was told that AE had to handle this request. - internally transferred the call to AE but I got the same previous automated response. I then wrote a letter dated -/-/15 to AE outlining essentially what I am reporting in this complaint and got no response. I believe I am due abatement consideration fro the following reasons : - It took AE - months to approve my payment plan with - - when all the other cards approved the plan in 5 business days or less- an unreasonable delay and one - said was unusual. -During the - months - - made payments to AE on my behalf that were actually in excess of the plan AE ultimately approved ( $580.00 vs. $650.00 paid ). -I maintained telephone contact with AE during the process ; informing AE that - month 's payment would be late because of my requirement to prepay -. I could not afford to double pay during this transition period. - The increase in interest charges is astounding and I would consider userousI believe I should be refunded the excess interest and the late fees.
