New Airtel broadband : wifi works, but not landline; airtel not accepting the fault
Had a new airtel broadband connection recently. The router and wifi works fine, but there is no dial tone in the phone instrument.
At another airtel broadband connection point, the SAME telephone instrument works fine.
The installation person wasn't even willing to accept this point and he said the line is working from their side and I should change the instrument.
So, to convince him, had to take him to a nearby place with someone else's landline to show that the instrument is working.
The issue is open for about two weeks now. Have asked him to try and change the router but he is refusing. Nobody is giving any answer on the issue.
Have told them that I'll escalate this to TRAI since they have already started billing for the service which they have failed to provide.
Any advice on filing the TRAI complaint?
