Indraprastha Gas Limited [IGL] — High Billing / Incorrect amount

Address:

New Delhi

Hi,
My IGL BP No. - [protected]
My Name - Mrs. Rita Ghosh
Resident - Vikaspuri, New Delhi

There is some issue with the billing amount generated this time for my connection. My bill generally comes between 200-500 Rupees. And this time my bill is 1554 Rupees? When I called Customer care, I was told my BP is also tagged to some Mr. Mahender. I also at times get SMS from IGL referring to Mr. Mahinder. But this connection is under my name - Rita Ghosh.
It is not possible, either the reading was incorrectly taken from my home or there is some system glitch or someone else is tagged with my BP number. Please check or else tell me who to talk at Nodal / Grievance department to register my complaint. I can send Meter Reading again and someone can come check but please fix this.
