Failure on service delivery!!!!

I hardly ever contact this bank for anything, probably only twice ever during tenure with them

On 24th May I called and spoke to Siphiwe. *** , informing him of the payment i made in error of R4000 to towards my car payment. He advised me to email the proof of payment, which I did on 25 May, I even received an email response saying that it will be processed between 3-5 days.

3 weeks later I still haven't received my refund. My banker also escalated the issue but still nothing happened. What pathetic service is this!!!!! Absolutely no urgency so solve a customer's problem!!!!!!!!!
