kamlesh,
You can use
RTI to get this matter clarified/sorted out.
File a
RTI Application with Bharat Gas and ask for:
1. Certified copy of the rules and regulations issued by Bharat Gas to its domestic gas distributors, which state that the consumer must buy the gas stove from the distributor if he needs a gas connection, otherwise connection will not be given.
2. Certfied copy of any letter or any other communication made to M/s Bharat Jyoti Agency,........,................, Nagpur, allowing them to insist to a new customer that he must buy a gas stove from the distributor before a connection can be give.
