[Resolved]  Tata Sky — inability to view channels

Address:

Thane, Maharashtra, 421301

I have annually recharged on 24/08/2017, but was unable to view any of the channels, so i immediately lodged a complaint where in i was told that a technician would visit my place and resolve the issue. Unfortunately nobody turned up. Thd next day i relodged the complaint and again i was assured the same but in vain. I am repeatedly lodging the complaint but no technician has so far resolved the issue.
My flat being located in the basement of the building, chances of acquiring range for a call is very low.
The technician is not being sent unless the call is successful.
My humble request is to send a technician by just notifying me the time of his arrival even if the call drops or else the issue would never be resolved due to which i would be at a huge loss having paid a lump sum annually.
Please comply with my request.
