<prompt> Human: So American Express asked me for a bank statement recently which I refused to send, and they closed my platinum card account. Later Citibank closes my bank account, and my credit cards. Today I see my BestBuy card, Bloomingdales, and Macys card is closed too as theyre from Citibank. Why is this happening???  <response>: Amex takes their financial reviews pretty seriously. Failing a FR or being unwilling to cooperate with one is considered a signal by other banks that you lied to Amex about some aspect of your financial situation. Now other institutions might assume the worst, especially if you werent a profitable customer or were marked as high-risk in their own system.If you dont want to comply with an FR then its a great idea not to sign up with Amex. As already mentioned youd have to contact Citi to determine the exact reasons they decided to sever your business relationship.
