Bharat Petroleum [BPCL] — gas cylinder delay/delivery to someone else

Address:

Prem gas agency katihar, Katihar, Bihar, 854105

Sir
My gas cylinder was booked on 20th aug and i made complaint of non delivery on 31st. My complain number 4671805.
Later i made enquiry of my request on 4th september and the customer representive said the complain number is closed with comment that delivery has been done.
But i have not received it yet. I asked him to refer it to higher authority.
I am not getting what is going on such a poor transparency. It seems some racket is working amf without any information, my complaint is closed. Still i am waiting for the gas cylinder.
A paid (Availing subsidy) consumer is facing such issue, so what would happen for an ujjala beneficiary. Most astonishing, i dont have a way to redress my issue.
