Reliance Bigtv — precook scheme is a big fraud

I have done pre booking on 1st march. After 45 days of wait, all I got is an SMS saying your booking has been accepted and installation will be done 45 days. It's cheating because they said only 30 to 45 days earlier. I cannot get to their call center as it is impossible to get connected. The single customer care number is never reachable by landline or mobile.
Looks like company about to fly away with cash of millions.
