Maharashtra Natural Gas [Mngl] — Bill not received till date

Address:	MNGL, Shivajinagar, Pune

We have a MNGL domestic CNG piped gas connection but we have not yet received any bills.
We have approached customer care vide email reminders and calls but in vain.
Also the customer care is not helping in a proper way.

My details are as follows:
