Dakshin Haryana Bijli Vitran Nigam — Bill paid through UPI but not showing in DHBVN Account

Address:	Hisar, Haryana, India
Website:	dhbvn.org.in

I paid my electricity bill using Google Pay UPI.
Amount got deducted from my bank account and received in DHBVN account successfully but it is not reflected in my DHBVN account and my bill is still showing as pending.
When I inquired in DHBVN they said they don’t have any record of payment and asked me to contact my Bank.
When I inquired with my bank they said transaction was completed and provided me with bank reference number and DHBVN account details where money was deposited.

When I asked DHBVN they said to deposit the bill again and shared some complaint details.
I don’t know what to do anymore.
Could someone please help me
