Reversal of a transaction

On the 25 july 2017 i transferred(IB) money to a standard bank account paying Mr*** and after 5 days he called a said that he did not receive the money and i asked Absa to trace the money and i was told it was deposited in the account that i provided. I asked Mr *** to check his statement from standard bank and he was told that the account has been allocated to someone else i asked absa to reverse the transaction . I sent an email and absa reponded that the matter will take 2- 3 weeks to be resolved and they keep on sending the same message after every 3weeks. After 3months they responded and say that the were unsuccessful to reverse the transaction & they can't even give me the reason why and i must contact the owner of the account or consult a lawyer. absa only responded when i do a follow up . I went to standard bank and explained to them and i was told that Absa must be the one that contact Standard Bank and request the reversal of the transaction to the amount of R3000. i don't have proof that indeed they consulted Standard Bank. I tried to call ********** 000 with no luck . Absa is saying to me that they cannot help their client i must go and resolve this matter by myself.My Ref No (EC ********** 4). Please help!!!!!!!!!!!!!!!
