Useless customer care consultants and service

Worst Customer service experience I have ever encountered in my 38 years. I will 100% not get new finance for my car again with FNB when the current car is paid off in a couple of months.

I made an payment in error of R28000 into FNB account and requested the monies to be refunded. I am not in arrears it was an honest mistake. Either way this is 2 weeks later and after speaking to 9 consultants and still waiting for Authorisation on the refund. Since consultant 1 did the request and advised the request is awaiting Authorisation and the money will reflect into my account within 3 working days. After 3 days I contacted consultant 2 which informs me that she has put in a request for the refund and it will take 3 days. So why did consultant 1 not do this. Then the exact same thing happened with consultant 3 4 and 5. All of them saying they are only now doing a refund request and they exculated it to the super visor. When you request to speak to the supervisor they are never available. They take your number confirming a supervisor will contact. In 2 weeks no one has phoned me from all 9 consultants that took my number. Anyways consultants 6 to 9 over the next week confirmed that the Authorisation in in progress and money will be transferred into my account within 24 hours. Still 3 days later and nothing. Spoke to the 10th consultant on 15 July 2022 and he confirms that Authorisation is still in progress and money will be paid in 24 hours. I did not accept this as 9 consultants before him said the exact same thing. I Was informed that he can't do anything more and that he will take my number and ask the supervisor again to phone me. I refused and said I will this time hold on for a supervisor till they are available as this is now a big joke of service. The consultant said it is not possible to hold and he promises that the supervisor will contact me back. For the 10th time nothing no feedback at all. Meanwhile my car is standing at a repair shop and refuses release until payment is received because 2 weeks ago I told them I'll have my money in 3 days. Now cost of storage is being charged on top of this You at FNB are all useless.
