I live in Tamilnadu and I opted for Big Tv a month back, I should tell you, they take atleast a week or even more to connect you to their service.
The Installation / Customer Care Department is Very Poor cos they dont stick to what they promise u over the phone as they are least bothered about it. After a week or 2 the engineers come to fix the dish and later after installation they promise that u can view the channels within 5 to 24 hrs since it takes time for activation, but all you have to do is just turn on ur tv everyday to find out if the service is activated and one fine day without any notice you can see the channels active and running. It should be ur lucky day .
And later after getting it installed, what I see is mostly they concentrate in North Indian Languages / Channels and there are no much channels for South especially Tamil. I guess they dont give any importance to Tamil and other South Indian Channels. And also the Set top Box sometimes gets hung or delays during channel change. This is what I experienced in BIG TV with less Satisfaction.I can give them a rating of 1 out of 10 for this product and support.
