Has anyone tried to cancel/return a DF once it has arrived at the store? I ordered an iPhone on launch day, and was able to buy one at the Apple store the following Thursday. I called to cancel my DF at the AT&T store that evening and the person on the phone couldn't figure out how to do it and told me to come to the store the next day. I went in on Friday afternoon and was told the phone had been shipped that very morning and they couldn't cancel it. Not only that, but once it arrived, I could only return it with a 10% restocking fee attached, even though the back of the receipt clearly states "10% open box restocking fee" and obviously, the box wouldn't be opened. The store manager also stated I could just take the phone. When I questioned him on me taking the phone out of the store without activation, he said it wouldn't be a problem. The phone arrived Monday. Cut to today, Thursday, when I go to pick it up. The manager wasn't at the store and the sales associated once again gave me the line of 10% restocking fee even though I pointed out the obvious. And he wouldn't let me take the phone home exactly as I predicted even though the manager said it would be fine. So I have to go back a 3rd time tomorrow to see the manager who will likely be as unhelpful as he has been so far. I go back to the question...anyone try to cancel/return a DF iPhone after it arrived? How did it work out for you?
