What should I do with an American Express Customer Service enquiry letter about a disputed charge?
Be sure to respond either by post, or by fax to the fax number indicated, with the requested documentary support before the reply-by date noted on the request. Be sure to indicate in the space provided whether Credit is due or no Credit is due, as supported by your attached documentation. If no reply is received from you by the reply-by date, American Express will deduct the Charge from your Merchant account.
