Directv Directsatusa Scammed me of promotion and fees Nationwide

I have signed up for Directv's $39.99 deal Xtra pack. I went through a local ratailer (ATT store) that deals with directv. Directv websited advertised free DVR upgrade to Genie. Did I get the free upgrade?! No! I did not! I ended up paying $127.28. Then when it came to installation, I was slapped with $75 custom installation. I told the technician from DirectSatUSA that it was suppose to be free installation. I gave them a check for $75 for the custom install fee. The check did not clear for a month. I tried to email DirectSatUSA about the check and the $127.28. I ended up stopping the check because I could not afford to have it taken out of my bank account. After I stopped the check, they tried to cash it after a month of not cashing it! DirectSatUSA have not responded to my messages. I have been trying to find local South Bend, Indiana and Chicago area DirectSatUSA office number and all I could fine was the one in Ohio where the main office is!!!! I do like Directv better than Dish tv and Comcast TV (comcast sucks in TV packages) Last month bill was $66.56. This month is $86.87. I am thinking about dropping Directv and just do over the air and the problem with over the air, I will lose the 4 channels I watch the most. I want my $127.28  back and have them void the check. My free 3 months movie channels are up next month. I want the 3 months to extend to til the end of the contract and lower my Directv bill below $65 a month or lower without changing my package and equipment. I would feel better if the bill was at $50 a month. If i have to cancel Directv, I will not pay termination fees at all which is like $400 or $600. If directv offers me free TV for a year or two I will take that.
