Videocon D2H — channels not working

Address:

560037

Unable to view channels after paying money.

After several complaints no one had responded nor came to resolve the issue.

Only few specific channels doesn't work.

When tried talking to customer care they say there is no issue in set top box nor my signal range.

Service engineer says cable issue/antenna issue/set top box issue. No one is an experienced technician.

No one resolves my issue. I just paid so much into account and activated so many channels which are not working.
