Hi,
I would like to inform you that Tata Sky DTH hikes rate in every six month and also providing very poor service. They are cheating to customer, if we discuss about that they reply in arrogant manner and say if not happy change your operator, There is a big amount needed to take any others DTH connection and if they do the same thing then how customer can use this service. Why they are not obeying any rule and regulation?
How and where a customer go to resolved such kind of issues.
