Poor service from FNB

I have a transaction with Comair and was notified by FNB that FNB clients would be re-embursed by FNB for such transactions. A claim was lodged on 21 June 2022. After numerous efforts to speak to my private banker, no effort from FNB was done to solve the issue. 12 emails were send to debitcard disputes department with no result. I am about to move my whole portfolio over to another bank.
