PhonePe — hdfc credit card payment with phonepe app is not reflected in biller account

Hi,

I paid my HDFC Visa credit card dues of Rs 20000/- through Phone Pe app at 08:25AM/04-Dec-2019. I got the bill payment status as succesful with operator ref ID[protected] and the same amount was debited from my bank a/c (UTR:[protected]. But the amount was not updated against my credit card account.
I tried another payment of Rs 5000/- through Phone Pe app earlier (08:20AM/04-Dec-2019) and later (10:30AM/04-Dec-2019) it was credited instantly. I tried to raise a customer complaint on Phone Pe and I was asked to wait for the next few days.

Could you please clarify on why the biller has not acknowledged this payment unlike the other two cases.

Thank you!
