Late account closure leading to further very expensive bank fees and rude costumer service .

I requested an account closure, was told it would take 5-10 business days. It then was not closed after four weeks. Thus I was charged R250 for the bank charges which is ridiculously high hence the closure of the account. When I contacted the FNB service suite I was told the matter was marked as resolved and I would be contacted regarding the bank fees. The account was finally closed two days later, and no contact regarding the refund of these bank charges. I then had to contact the service suite a third time where the person helping me was rude and unhelpful disconnected the chat before giving me any helpful advice on how to proceed. The service I've recieved in this matter is absolutely awful and if anyone ever askes I will not be recommendingn FNB
