So i received the financial review letter from Amex this week I have the centurion card. Have had an Amex card since 1980. I have never once had a late payment and always paid in full. I am averaging around 130k a month in charges. The women on the phone said I had an 80k balance and they were concerned? I told them i would send a check early if they wished. They wanted a copy of my tax return for last so many years and a financial statement. I told them NO. I am a very private person and have no intention of sharing this info with Amex. I think this is ridiculous. I have been a paying customer for over 30 years. Any advice? what will come of this. they threatened to limit my centurion card? isn't this a no limit card? I have half a mind to take my 30+ years of incredible business elsewhere and give the 6k in fees a year for my cards to charity.
