Tata Sky — No signal problem continuously coming from the starting

Address:

Dehradun, Uttarakhand

Start from one month of Tata sky dish buyal, problem of "No signal" started coming. We complained many times, service person even came did what he could do but was unable to solve the problem completely. They even changed the box once with another but problem again started coming after few days. Now the problem become frustrating and tata sky people seemed useless and hopeless. So I request to rectify the problem by any means else like many other customers one more will loose trust on tata sky.
