Paytm Mobile Solutions — money transfer from one account to another.

I have sended the money from my paytm bhim account to hdfc account holder name rs4000 but the beneficiary has not got the money because I have entered the wrong account number but the name and ifsc code was correct. I have complained about this to paytm but they are not replying I have complained about this to hdfc bank they have said if paytm complained about this to them then they can hold on the money in that account in which I have incorrectly sended the money. But they are not replying then how can I can I resolve this
