PhonePe — money debited from my account via phonepe but not credited to beneficiary account

Address:	Jaipur, Rajasthan, 302017
Website:	Phonepe

I have transferred 500 rs to rrb as exam fees through phonepe. It shows transaction successful but on rrb site it is showing "failure" in payment option. I have contacted phone pe customer care and also registered on their app but still, it's not resolved. They are saying we have successfully done it but rrb site is still showing failure. As a matter of examination registration, its time-bound so let me know as quick as soon but they are irresponsible and wasting my time.
