Maharashtra Natural Gas [MNGL] — Bill not generated due to which not able to find BP number on mngl website

My BP number is 50097299 for which bill is not generated till date due to which I am not able to find any record for my BP number on mngl website for bill payment.

Even after multiple complaints and follow ups with customer care and personally visiting mngl office issue is still not resolved.

Last complaint number which I registered was 10550651 which was assured that will get resolved in 3-4 days but its been month and still there is still no update on it and issue is still not resolved.

Customer care and bill department dont answer the call.

I am frustrated as a consumer with such worst customer service.
Please resolve the issue since I am not able to pay the bill.
