Money paid incorrectly

I have made an incorrect payment on the 28 July 2019. it was a direct payment from Capitec to Absa. Wrong nr was *** and the correct nr was ***. On the 29 lady called Capitec about the payment in return they call me. I informed then I will go to the branch to do a reversal. When I got to the branch the say it is a direct payment I must go to Absa. I went to Absa they refer me to Digital to Digital and complaints at Absa. I have been up and down between the bank and receive no joy. The client called me whose accounts the money was paid into. she has given Absa authority to pay the money back still they refer me back to Capitec Seems to me the bank want to keep the money. See my reference number. Ref nr ABSA C-***9 Capitec ***8 or ***.

I would like to have an answer we do not talk about small money it is R24 500.00.

By when Can I aspect and answer cause I do not know which way to go
