Bhim App — amount is debited but not credited to beneficiary account

I have sent 4800rs from my account by bhim app but amount is debited from my account and not credited to beneficiary account on date 19dec2018.
My account is in icici bank and beneficiary account is in sbi.
I complained in bhim app but they didn't respond properly.
I tried to complain in sbi but they didn't even listen to me and disconnected the call.
Please help me out of this.
