Karnataka Bank — HP GAS Cylinder payment done thro PayPhi - amount deducted through UPI but not received at payphi - to be returned back

Y.day evening I have maid payment for my HP-GAS cylinder delivered to me,
through HP-GAS scan&pay PayPhi.
It got scanned, amount was also deducted from my account.
It showed "Address verification failed". I didnot get a payment-success symbol+message .
Amount is Rs.812/-, transaction under UPI:[protected]:PayPhi.[protected]@icici()UP dated 07/04/2021
(my amount is deducted from mobile no.[protected], bank App- KBL Mobile Plus, Karnataka Bank, Karnataka State)

In the HP-GAS payment status (in payPhi screen) - it was showing "payment not yet received, to be paid".

We had to make payment again through GooglePay, it was success & payment was done.

Hence the payment done thro' PayPhi of Rs.812/- has to be returned back to me.
I spoke to Karnataka Bank Customer Care y.day, asked them to cancel/hold/return this amount, but in-vein.

Kindly get back this amount for me.
