Gujarat Gas — Paid for a connection before one year but didn't get it.

Address:

33-HIG FLAT, B-BLOCK, NEW AMRITSAR

We have paid before one year for a PNG gas connection but didn't get the connection. We have tried calling the employees of this company, but they didn't do any work. We have also called on customer care but they didn't resolve the problem.
We are regretting for paying for a connection to such a company whose employees don't know how to do their work. We want the connection as soon as possible. If not possible we want the money refunded with interest. Please resolve the problem.
