Poor customer service

I have made a mistake and deposit funds in to their ABSA account that I ONCE PAY helping my brother to make payment. I called several times requesting for a refund and send all required documents via email no response. The call center people doesn't want to work. The just end calls and tell me what to do without listening to my query. I called asking them to check if they receive my email with all the correct documents. One agent said I must have customer code to request refund while I have the proof of payment and proof of account with my ID sent to them. They are not telling me same thing. One said it will take 10 working days and one guy said it will take 48 hours. This all heppen on the 26 March 2024 until today I never get my refund. Their customer service on the call center I poor. I need my money like I said it was a mistake since they were added to beneficiary and I made immediate payment.
