Maharashtra Natural Gas [Mngl] — Meter reading submitted via whatsapp still processing the average bill

I get the bill of 908 for the month during may 2020. But I was not there at my home from May 2020 and I already sent an updated reading to the MNGL whatsapp number [protected]. Still I get an average bill of 908 rupees. And after that in July 2020 I get the updated with the addition bill of 1911 (including late charge 100 for previous bill). I again send an updated meter reading photo to the whatsapp number in july and august month again. But no one is reply me on the whatsapp number.

So please take my complaint and resolve my bill issue. And please close my connection temporary until I did not add a request to start again the meter.
