Maharashtra Natural Gas [Mngl] — generating bp number mngl

Address:

Blossom N Springs society, Baner Pashan link road, Pashan, Pune - 411021, Pune, Maharashtra, 411021

I've been trying to generate bp number for mngl pipeline that out society has. I talked to number of agents on their toll free number and all of them are saying write an email to our customer care and they will generate if for you.

So i wrote email with all the necessary data and they are replying that you can't do it on email. You have to visit the office.

So many days and i still don't what should i do or what is the correct process.
