On the packaging of the Amex gift card it states that " funds replaceable if lost or stolen '' ( and i am including the image of the packaging as well ). The customer service at Amex refused to help me. They stated that their " system '' does not recognize the receipt number or the account number of the card which is on the receipt as well. I have called the Amex customer service 4 times and each time they refused to help. I am completely at a loss of what to do. I felt safe purchasing the card and sending via USPS because of the refund guarantee stated on the packaging.
