Query: The WORST service ever(still haven't received the phone)!!!

I ordered the phone on 12.17.03 and was promised receipt in 3 business days. After unsuccessfully attempting to reach a customer service rep for over a week(waiting on hold for over an hour on 12.23) I was told on 12.29 that my order was indeed submitted, there is/was no way of knowing when the phone would arrive and that my order could not be nullified.I called again today, 01.13.14, and was given the same story.AT&T is the absolute WORST and deserve noone's business...end of story!
