Bharat Sanchar Nigam [BSNL] — not resolving my complaint properly

I already complained 3 times but the company didn't solve my problem. My problem is that i can't get hsdpa connectivity in my home.
The docket number of my complaints are-
1. 1j10398080 on 10/10/2017
2. 1j12308455 on 12/10/2017
3. 1j19374470 on 19/10/2017
I also informed appellate authority about it.
Actually i got the 2 point signal in last 2 date but today i faced the same problem.
Please help me sir as none of their representative answer me properly.
They do nothing instead of registering complaints and after 2 days i got the message that your docket number has been closed but actually my problem is not solved.
Please help me to get rebate as they didn't solved my problem within 3 days as per trai's law.
