I once ordered a 20' cable on Amazon, a 10' was delivered. I double checked my order to make sure I wasn't the one who had made a mistake, then returned my 10' in exchange for a 20'. They sent me another 10' cable. I contacted customer service and told them something in their process must be wrong, to please carefully ensure that they understand I want a 20' cable, and ensure that a 20' cable is sent to me. This probably went unread. They sent me a 10' cable, then asked for a nice review. I returned the cable for a refund and took my business elsewhere.
