HDFC Bank — payzapp transaction successful but money not paid at reliance retail

I tried to pay bill at reliance mart using bharaqr on payzapp. Money got debited twice but reliance did not receive the money as it showed time out.
I opened complaints both at reliance mart and payzapp. Reliance said they did not get the money from payzapp. Payzapp said transaction was complete from their side contact the parent bank.

Screenshot of payzapp transactions and letter from reliance retail are attached.
