Maharashtra Natural Gas [Mngl] — Bill not produced and Online Registration not allowed

Hi TEam,

I have taken MNGL connection 4 months ago, Still i haven't received any Bill so i have connected your customer support before 1 month Ago and send my Meter reading screenshots to them, after lot's off follow up they send 1 person and he has taken meter reading on 21st August.
but still nothing happen.
Same time when i am trying to register my self it's say's BP number not exist which is given by MNGL.

I hope your will fix this issue now on priority. My BP No is 50303629
