Maharashtra Natural Gas [Mngl] — Billing (detailed bill copies not received)

At the time of purchasing mngl connection, I have been told that a deposit of Rs. 6500/- would be required for each connection.
Currently, I am having single connection and had already paid Rs. 500/- cash to mngl executive and he told company will adjust the remaining deposit of Rs. 6000/- in mngl bill.
Till date, I am just paying bills online and have not received any itemized (detailed) bill.
You are hereby requested to provide me the itemized (detailed) bills for each of the billing receipts to make this scenario much clearer to me, so that, I can make the future payments smoothly.

Thanks,

Abhijit R. Wadekar
