[Resolved]  Bharat Petroleum — Not able to submit complaint. Customer care is of no help

I had placed an order for cylinder refill on 10th April, 2022.
It has been 39 days since my order but I haven't received the refill cylinder.
I had raised this issue in customer care 3-4 times but it is of no help.

Tried submitting my complaint on customer feedback page but its not working.

Neither they are delivering the refill for gas cylinder nor they are allowing to raise any complaint in their website.
