Hindustan Petroleum Corporation [HPCL] — online payment issue and poor customer service

Address:

411019

Today i have booked and paid rs 704.5, for a gas cylinder.
Payment done by debit card, through hprefuel app.
Confirmation of booking not received from hprefuel server.
After wasting 3 hours with customer care, finally they issue me complain number as 450699. My consumer number is 646565.
I have to book cylinder asap, but they said first settle your refund issue, and then book cylinder.
Finally i book cylinder by online number, which i have used previous.
These servers of government companies have often have issue and held our payment and harassing unnessary. Refund my money asap.
