Maharashtra Natural Gas [Mngl] — Wrong Billing BP No. 50000395 Bill No.[protected]

I have been continuously chasing MNGL team to rectify the above invoice which includes Rs. 100 as late payment charges. I regret to advise that around 4 days back i have received hard copy of both the bills together, how i can pay in time without proper intimation and bill copy from MNGL. I have been regularly paying the bills which are received in time and before due. Request to the concern team members to immediately correct the bill and share the copy. Please do not harsh the consumers due to your inefficiency for not delivering the bills or delivering late 2 bills together.
