Maharashtra Natural Gas [Mngl] — bill not generated 50127938

Address:

Pune, Maharashtra, 411028

My mngl BP no is 50127938
I have got new connection around 5 months before and never got bill.
Followed up with mngl multiple times.
Customer care says issue will resolve but never resolved.
Online status while paying against the BP number shows record not found.
Hence can't have a look and pay bill there online.
It would be great if get this resolved
