Many different U-verse cable problems.

I am writing this post because of cable problems that I have that no one can resolve. I have had AT&T U-verse since 3/5/09. When we got U-verse there were some problems at first, then everything seemed to go smoothly for a couple of years. Recently a lot of different things started to happen. I recently had 15 service calls to my house; every tech that comes tells me something different is wrong. I have had a many different problems; a lot of pixelation, live TV will pixelate then freeze, the TV will go black then say a message lost signal, the TV will seem to have interference with static lines across the screen. The dvr will not record properly, sometimes part of the show is missing, pixilation, the picture freezing, the sound missing, and peoples voices do not match there lips when they are talking. Often you cannot pause, rewind, or fast forward on the dvr. When I went on my computer that’s hard wired to the modem the one TV that is hard wired from the modem went black and said lost signal, this happened multiple times. One time a line tech was here he disconnected the cable from the house outside and I still was watching TV on my 62 inch big screen, which at the time had a wireless cable box. It must have been picking up a signal from a neighbors house. I called him in to see the cable was still working. He couldn’t believe it and called a tech to check it out. The techs that came out have replaced modems; dvr’s, cable boxes, added a net gear Ethernet splitter, they said my coax cables were bad then took out 2 cable boxes and added 2 wireless boxes. At that time I was picking up a neighbors signal then they removed the wireless cable boxes and installed cat 5 cable to the 2 boxes. The last tech that came out said what do you want me to do? Did not have a clue as to what was going on with our history of past repairs or what was replaced. My wife said he needs to finish the cat 5 wiring the last tech didn’t complete. He said he will have to charge us. We were not charged by the last tech because of all the problems we were having. He then said there were no problems with the cable cat 5 wiring. My wife showed him a dvr recording with pixilation, freezing, and no sound. He said that shouldn’t do that. My wife called me at work and I explained over the phone as to what was going on with the cable. He said again that shouldn’t do that, he doesn’t see a problem with anything. He then got into his truck and left, did not replace or do anything. As of today all the dvr problems still exist. The dvr will not record properly, sometimes part of the show is missing, pixilation, the picture freezing, the sound missing, and peoples voices do not match there lips when they are talking. Then once when in the recordings menu the dvr beeped and the font size changed to a larger size on its own. You could not read it because it was off the screen. Live TV will pixelate then freeze. I pay a lot of money for this service $215.00 a month. All I want is an answer; can someone repair the cable in my house? I need to know, if not I will go with another company. You should not have to deal with these kinds of problems with your cable TV, phone, and internet service.
