Mahanagar Telephone Nigam [MTNL] — Dolphin signal and call quality has become horrible

Address:	Mumbai City, Maharashtra, 400104
Website:	mtnl.in

I am using dolphin service for approx. 10 years now. For last 1 year or so, service has been continuously deteriorating. Weak signal, no signal, call drop, one way sound - it has become horrible as of date.

I have repeatedly complained at mtnl customer care helpline but there hasn't been any follow ups/actions from mtnl. My first complaint was registered on april[protected]Case #1123765) and its been almost 3 weeks since then. Every time i call customer care to follow up, a new complaint is registered instead of resolving my original complaint.

They have given me 4 complaint numbers since my first call but the problem stands as-it-is. Complaint numbers: 1123765, 1127347, and 1131550 are through customer care helpline while complaint number: 169873 is through online complaint system.
