I bought a pair of shoes on July 23. The item was paid for in part by an Amazon gift card, Amex rewards points, and an Amex charge. Amazon was unable to deliver the item and so made all the necessary refunds. On August 3, I attempted to buy another pair of shoes, but was not offered an opportunity to use my Amex rewards points. I contacted Amazon to learn why and was transferred from one clerk to another for 45 minutes. None of the five clerks to whom I was transferred could answer my questions. I cancelled the order for the shoes and will not place another order with Amazon due to the incompetence of your customer service employees, none of whom could answer my question about why I was not offered an opportunity to use my rebated rewards points. The entire experience made shopping at Amazon a headache. Why bother?
