The payment is approved .. but the recipient didnt got money

I had transferred money through Bhim app on 4 nov 2018 . Money was debited from my account but not credited to other person account. I have lodged complaint two times but no response. Everytime complaint number is issued but no revert from bhim app customer care . Even sbi refused to refund my amount
