[Resolved]  Seth Gas Service, Inside Sultanwind Gate, Amritsar — Cancellation of Old Domestic Gas Customer Card

My consumer number is SE-15097 at Seth Gas Service, I/s Sultanwind Gate, Amritsar (Punjab). We have been issued Gas Booking Card in 1995. Now they have cancelled our Booking card saying its the fake one, whereas the card was issued by the same agency. This Agency was caught in Scam earlier also and are doing the same again by using the Domestic Gas Commercially and Selling the Domestic Gas in Black saying that there is lot of shortage. We donot have any other connection. Agency is not issuing me another copy nor transferring the copy issued by the agency on my name. If the the Booking Card is Fake why it was issued to us.
Kingly let me know what i must do.
