Terrible Customer/Tech Service

This is by far the worst customer service I have ever experienced. I am usually pretty patient and understanding when it comes to tech issues because I actually worked in that field for a while. Here is my latest experience with AT&T.

Day 1: I was having troubles with my U-Verse tv. The image kept freezing on screen. I am somewhat tech savvy so I tried to reboot the system myself. No luck. That's when I made the initial call to AT&T's tech support. The agent walked me  through some troubleshooting and in the end determined that it was my receier/DVR. He scheduled an appointment for the next day between 8am-noon to have a technician come and swap out the piece.

Day 2: The technician never showed up that day and didn't call to let me know he couldn't make it. I had to call tech support myself to reschedule. When I called, the agent said he could not find any record of a ticket being submitted or a dispatch being called. I told him the agent I spoke with the day before said someone would come out and swap out the piece. This agent said, "Well if the technician comes and determines that that's actually the problem, then we'll switch it out. But he'll want to run some tests first." Fine...whatever...I just wanted my tv fixed. I made a second appointment for the next day from 4pm-8pm.

Day 3: The technician never showed up that day and didn't call to let my know he couldn't make it. I had to call tech support myself to reschedule and see what was going on. The agent said his records showed that a technician did come to the apartment, spoke with the customer, ran some tests, and concluded that everything was fine. I told the agent this was completely untrue. I was home all day and no one came to the door let alone fix my tv. Regardless if the agent thought I was lying, my tv was  still not fixed. I made a third appointment for the next day from 4pm-8pm.

Day 4: It was 7:45pm and no sign of the technician. I called tech support again and the agent called the dispatch. They gave some excuse that they were low on technicians. Which I get, but they still need to call their customers and let them know. The agent said that dispatch was supposed to call me later that night or the next morning to reschedule. 

Day 5: I never received that call. I called tech support again and asked to speak directly to a supervisor thinking that a supervisor would right the wrongs. This supervisor (Daniel) was not helpful. He never apologized for my problem and could not offer me a solution. The only thing he did was schedule a FOURTH appointment for someone to come out. I asked him, "What happens next if the technician fails to meet this fourth appointment?" He said to call back and schedule another one.

So I now have an appointment two days from now (we'll see what happens). Which means this issue has been going on for almost a week now. I'm tired of hearing excuses and having to do all of the work. I don't have time to sit at home every night waiting during the 4 hour time slot for the technician to just not show up. This is the worst customer service I have ever experienced. And I am shocked at the supervisor's behavior. The other agents that I spoke to were more apologetic, sincere, and willing to help than he was. 

At this point, I don't want any more excuses or chances. I just want the service that I pay for to be fixed.
