My story is : I have not receive AMEX statement nigher on-line notifications for two month in fall 2008 then they send me a letter stating that that because i did not pay my bill($14.62), they adjusted my credit limit to minimum and they demanded payments right a way. I call them, AMEX Customer Service Representative(CCR) confirmed that they sent my bill, but received it back! She figured out they AMEX sent a bill to wrong address but refused to bring my credit card limit back! I was AMEX card holder for over 10 years, never was late on my payment and always pay my balance in full. Well, as a remedy I closed AMEX account and wont apply for their CC ever again!
P.S> Week latter I received a named mail from AMEX asking to apply for same CC. What an idiots!
