Capitec gave other person my money, help

Money was transferred incorrectly to a cellphone number because of one digit wrongly typed. The bank said they must get hold of the other person, then they can only transfer my money back. They said they phoned me on the 04/05/21 and send me an SMS, but they never did. I went to the bank on the 01/05/21 but the bank was closed. Then I had to go on 03/05/2031, we were on the phone to head office but with no results, I also went back to the bank and still no help. This was a R1500 how can Capitec not help and just reverse my money back in my account since it came from my account, how difficult can it be??
