American Express Travel Related Services Company / expired gift certificates

I mailed to American Express 2 expired gift cards for $25 each. I was told that they would mail me replacements. Instead they send me a form asking for a copy of a utility bill plus a copy of a government issued photo I.D. and if they didn't receive this information within 10 business days of this letter(the letter was dated on Oct. 23rd and I received it on Oct. 30) they would close my case which means that they would keep my money. This is a scam. American Express should be sued for fraud. After reading other customer complaints I realize that this is how they hope to defraud customers of their money.
