Hassle-Full Experience with AT&T within first 2 months

Recently moved from an apartment to another as a Comcast customer.  I purchased the Uverse 300(2 year) and Internet bundle(1 year) at $105 on Jan 21 and shockingly my first bill was $295.  I was also promised a $150 gift card to which they sent me $50.  Foolishly, I had activated Autopay because I ASSUMED they would not vastly overcharge me.  Apparently, I was being charged for HBO/Cinemax to which I was supposed to get free for 3 months and none of the bundle discounts were being applied to my bill.  I called the customer support line where a customer service rep said that the only way to fix the problem was to ship my receivers with UPS and have another technician come and install new receivers.  I had no problem with the service, I had a problem with the bill and insisted that it couldn't be the only way to fix this problem.  He even promised a $200 gift card for my inconvenience.  That rep finally transferred me to another rep where she proceeded to change my next bill to the correct base amount of 105...however it only adjusted my next bill, not any bill after that, nor did they even credit my account for the first bill of 295 that had already been taken from autopay.  After many hours on the AT&T hold line and talking to customer service reps that couldn't help me I finally decided to just go to the company store.  A very nice employee helped me out, but he also had to call the customer service line to get everything rectified.  In short, all these problems have occurred in less than 2 months of being an AT&T customer.

This has been a process.  Bottom line is I'm happy with the product, not happy with the customer service.  This has been a huge headache, inconvenience, and I am not even receiving anything in compensation for the hours wasted for a mistake that was caused on AT&T's end.  I'm still waiting on the missing $100 from the rewards card that suppposed to be included in the original purchase and I assume I'll never get anything else for this aggregious error.  

Has anyone else had as many problems as I had?
