Amex Credit Card Complaint

Amex Credit card department,

New York

I purchased a $75.00 Amex prepaid gift card as a gift for my son. When my son tried to use the card he was told by the cashier that the gift card was never activated when purchased. I have been in contact with Amex numerous times to resolve the situation. Each time I have been in contact with Amex they have thwarted my efforts to recoup the money. I sent Amex clear photocopies of the gift card and receipts. They even ask me to send them a copy of the store journal which I went to the store and they had to contact their corporate headquarters. I followed up by fax and mail ( certified ) with very clear color copies only to be informed again that the documentation was illegible. Amex is giving me the BIG RUNAROUND after attempting to recoup my money. I have reviewed these gift cards only to realize that many people have the same problem. Please help. I have exhausted my options with Amex. I have documentation to send if you would like to review. Thank You ... ..
