I has been using dish Tv for around 6 years. I never had a bad experience with them, I shifted my house 2 times in between, they had been very prompt in all my quires. only once when they came for re installation I was not happy the way the technician was working. it looked like he was not capable or was not experienced. for which I had given a complaint also.
But now im using Tata sky as in my society every body is suppose to go with tata sky I guess because of the corporate tie up. Now when have started watching Tata sky we realize that the picture quality and sound quality is far better in tata sky than dish tv.
