Hindustan Petroleum Corporation [HPCL] — refill payment issue

Hi, i, hp gas customer, having customer number 683744, tried booking a gas cylinder yesterday on 8th april around 11 am.

The booking was confirmed and i had received a message with booking confirmation and payment link. I used the link to pay the amount rs. 744. Though the amount was debited from my upi account (Transactions shows approved and successful) but it was not credited to hp gas; the payment page just expired. I re-tried the payment but again i encountered the same issue where rs 744 was again deducted but was not credited to hp gas.

It has been more than 24 hours but neither have i received the refund nor i see any process initiated by hpgas to refund the same.
