Money Transfer To Wrong Beneficiary Account

I had done money transfer of INR 49000 to wrong bank account. I had done complaint immediately to the bank and the account of wrong beneficiary is dormant and as per my request the amount is blocked by bank. Now bank is approaching wrong beneficiary account holder to give consent letter but that customer is delaying the matter. He had not denied to sign but not coming to bank for signing the consent letter. It is now about 1 month of this incidence What can be done now.
