[Resolved]  Tata Sky — delay in service and no cooperation

I’ve been using tata sky since 4 years. Since 1st march 2018 i’m facing a problem of set top box shutting off automatically. I made a complaint many times every time i’ve to do master reset. This continued for 15 days. Then a technician visited and he has done software reset and assured that problem will not come again. But after 2 hours again same problem was there. I again called customer support then they said you need to change set top box. That was done on 29 march 2018. And now from 31 march again there is no signal. Out society is having common dish installed and every other flats have signal except mine. After again making complaints every time tata sky representatives says you will get solution in 2 hours but again when i call after waiting for 2 hours they say my complaint is not registered. This is not expected at least from a company like tata. Very disappointing
