Get Your Late Charge and Financing Fees Back
Credit card companies will never admit that they will reverse financing charges and/or late fees once per year, but they do. Don't waste your breath on the first customer service agent that answers the phone, they generally lack the credentials. Ask to speak to a supervisor and then plead your case (examples: Online payment wasn't working, you have been traveling a lot recently, your bill did not arrive in time, you always pay your bill in full and would really appreciate a credit this one time, etc.). If you don't get anywhere with the supervisor, ask them to transfer you to someone so you can cancel your card. Now you can do the same thing with the retention department, remember they want to retain you; the ball is in your court.
