Nedbank has no service at all

On the 22nd of January, I received an sms from Nedbank that an amount of about R3800 was paid into an account I closed on the 13th of January 2021. I went to the bank on the Saturday, 23 January 2021 just after 9 in the morning, and was told by the cashier at number 5 at Centurion Lifestyle, that she had to open the account, and asked us what the account nr was at Standard bank, which we gave her. She completed the transaction and said it would reflect in that account at Standard Bank on Monday 25th of January. The money however didn't reflect on any day since then. At some point a woman contacted me, named Yolandie Fourie, and asked me to sign a completed form. The date was 1 February 2021. I signed the form on the same day, and mailed it back to her. Two days later I sent another e-mail, to which she rep**** saying it would take up to 5 working days. Today the 9th I sent another e-mail asking why I still have not received my money, which was not answered until late afternoon by her, stating that they are still trying to retrieve the funds and her Manager Neran Naidoo will contact me. My question is once again, why did I have to keep on following up? And it seems that Nedbank just continue to do what they have been doing well, and not provide any service at all! I am really fed-up! Nedbank, that money is mine! Pay up!
