AT&T Horror story - Switch carriers while you can

So I ordered new service with AT&T yesterday (new phones for my daughters birthday) and did the In-store pick up option because I'm out of town and won't be able to get the package delivered to my home, neither can I pick it up. The selling point for me was that AT ANYTIME I would be able to add an authorize user and they would be able to pick it up for me. Cool, great, wonderful. I was assured after asking atleast 10 times that I would be able to add an authorize user to pick up my package for me. So I get the E-mail saying that my order is ready for pick-up so I go and try to log in to my account so that I can add the authorize user. Lo and behold.. I can't do it?! Why? Because the account is not yet active therefore I can't add anyone until I pick up the phones and activate them. Keep in mind people that I spoke to 2 sales reps AND a supervisor BEFORE I placed the order that assured me I could do it this way but they leave out that little detail?! And I know you guys record phone conversations, you can go back and listen to me clearly being reassured multiple times I'd be able to add a authorize user. AT&T has the most incompetent employees out of all cell companies, even Metro PCS and that's saying something. Not to mention the wait times. I spent maybe 5 hours on the phone yesterday minimum and no one can resolve my problem. No I don't want to cancel the order and have it shipped, my daughters birthday is TOMORROW and my items are just sitting at the store and I cant do anything about it. This has to be THE worst experience ever.
