Bangalore Water Supply & Sewerage Board [Bwssb] — please support - online payment discrepancy

I used the website https://www.bwssb.gov.in/login in quick pay mode to make the below payment of my outstanding bill for bangalore water supply and sewage board.
I made a payment of rs. 6685.69 through google pay. (See attachment). My rr number is e-224737 (See attachment). This transaction was successful in google pay and the amount also got debited. However, your website showed that the transaction has failed with no proper details (See attachment).

It has been a rather frustrating experience for 3 days to see that the amount is clearly debited from my account but your website still shows that the transaction didn't go through.

Please process this transaction or refund my amount at the earliest.
