Bharat Petroleum [BPCL] — Mentally harass by the office staff

Address:

Town-sarthebari,Dist-Barpeta,state-Assam

Today I went to Baikuntha Bharat gas agency which is situated in Town-sarthebari, pin-781307, Dist-Barpeta, state-Assam.
I requested for new connection and asking them to let me know about the new gas connection charges.
They told me that I have to pay 5000 rupees for single cylinder where Gas stove is mandatory to purchase. I said that I don't have any requirement of gas stove as I already have one at my home.
They forced me to purchase and said that if don't want to buy then show them the gas stove bill.
I said that I am new in sarthebari and recently shifted on rent.
They told me that without purchasing gas stove, they will not entertain me and will not send my documents to Head office.
Is this the way to deal with customers? The behaviour of the office staff is so dangerous.They doesn't know how to behave a customer.They behave rudely to the consumer.And they also give abusive gesture to the women.I have seen that the office staff was remins drunk
