AMEX sucks

AMEX SUCKS big time.
After 3 years of continuous use of AMEX, I was really amazed at the way they handled a 'change of address and phonenumber' issue; by putting all my credit cards to hold on financial review. Apparently they got ticked of as I was purchasing too many airline tickets including one to go to India....I didn't understand the issue as all the cards was paid up-to-date and the travel was mainly professional.I did what I could do. I paid off the debts and cancelled both the cards....thats my way of saying NO to the nuisance that's AMEX.
