Still no Refund or Proof of Payment

So i have been waiting for a refund from 08 October 2018, my account was settled on 04 September 2018, it took a month to get my account updated, they then realised that there was an overpayment. A gentleman by the name of Viwe Bokveldt was assigned to investigate, 6 working days later he calls me and tells me that his finance team will be making a payment on 07 November 2018. I did not receive this refund, and asked Viwe to please provide a proof of payment, he did not respond! I then wrote an additional complaint on Hello Peter, a lady by the name of Nondi Tsholoba was assigned to assist with my query, she called me on 16 November 2018 to assure me Capitec's finance team said they will make payment the afternoon of 16 November 2018, however if the payment does not reflect, i should send her an email advising her and she will get a proof of payment from finance. Yesterday, 19 November 2018 i sent Nondi an email to please request a proof of payment, i have had no response. And now it is has been 10 weeks since i settled my account and everytime i complain i get a silly response that someone will be in contact within 5 working days! This Bank is a ****, you keep your refund money that belongs to people just to gain interest, the money is not yours to keep, and your response time is pathetic, clearly you have *********** people working for this bank that the need 5 working days to respond to something as simple as a refund, someone at some point had to have compiled an investigation and yet everytime they are investigating all over again, do you not keep records at all? And i now have 8 different reference numbers, which are all useless! I need a phone call from a director now, this is terrible service, i wouldn't advise a single person to ever take a loan or even open an account with the useless Bank
