Shocking service and have been **** to by FNB

I was sent proof of payment from a client on 27/09/2024 from an overseas account into my FNB business account. On 01/10/2024 I followed up with FNB Forex for the status of the payment I was told that the account holders name was incorrect and had to be refunded into my clients account and this had already been logged for the payment to be returned on the 01/10/2024 and the e mail also stated that it would take 5-7 working days.

I followed up again today and received a proof of payment from FNB forex that it was only done yesterday 08/10/2024 and we must now wait another 5-7 working days. This is not a small amount of money. The client had to pay the same amount again using Paypal so he is now short of double the amount and must wait 5-7 working days once again. In the mean time how do I explain this catastrophe to my client? I have been holding on the phone for ages for the team leader who was on a call then got told they are in a meeting. This is the first transaction with this client and I am in the process of liaising with them for future business but I am afraid this will sour our business deals due to the bank I use.

At this stage I want to go to the nearest FNB brank and close all my accounts with them immediately and move to another more competent bank.

I am livid.
