African Bank not willing to refund me

HI I am very disappointed with the service i, received from African bank customer care . I requested a refund for money that was incorrectly deposited in to a loan account that was already settled , but since the 8 of February 2023 till to today i have still not been refunded and do not receive any feedback from African bank customer care . i phoned African bank customer care on the 8 of February 2023 , requesting a refund and was given a reference number ***) and told to wait 72 hours . after 72 hours and numerous phone calls , the ticket was closed , without any explanation . on the 13 of February i was told that another ticket was logged and i got wait another 72 hours , but also received no feedback after this time . on the 15 of the February 23 i called the call center and spoke to Motlatsi , he escalated the matter to his team leader , Gugu Walaza and she promised to escalate the matter and provide me feedback , which she did do . i forward proof of payment to them , but i am still have not received my refund or any feedback from African bank customer care .
