Viasat Exede, WildBlue Sales misrepresentation Nationwide

Sales/installer misrepresnted the total service that was explained to me then was provided. I was not told that I signed up for a promotional product that was going to change I explained that I wanted to stream TV from the internet to eliminate satellite tv by using Netflix, Hulu,etc. I already had been a WildBlue Cust for 6+ years(same company. I was told that another 2 yr contract was needed. Did not know why , but agreed. I was told about the service, 50g per mo, 59.99 mo 2yrs, and that it would change in July and get better.  I signed an installation completion sheet and 1 of the guys was showing me stuff on my computer and the other guy was packing up, then they were gone and I then realized I didnt have a copy of what I signed and didn't have a contact # for them  Exede said they didn't either and could not supply a copy for me. First bill came and there was an equipment rental charge. I contested saying that my total charges explained did not include this charge adn again I asked for a copy of the signed contract which they couldnot provide. this went on and I believe I got 1 $15 credit. then the monthly service went up twice.  I called to complain many times to no avail.  I finally called again last week and was given info to chane my plan and I chose not to and wanted to speak to a supervisor. the agent got really snippy and told me that the supervisor wouldn't do anything more than he concerning the lies I was told about what I 'thought' I purchased and what I got. I insisted to speak to a supervisor and he got snppier and said he would contact one to see if they would talk to me. he came back on the line and told me they would not take my call. I insisted again and was simply put on terminal hold.  I hung up after 19 minutes.  I went online today and my service was indeed downgraded to a 10 gb plan without my permission. I called customer service (or lack of) and was told their systems were down and to call back in a few hours. This is totally unexceptable sevive on all levels
