DONE WITH FNB

I called last week Friday for assistance with an overpayment / incorrect transfer on my side . I was told that it would need to be escalated to the team leader and i would receive confirmation that this has been refunded . Nothing was received . I then went onto FNB'S app , and sent a complaint or request through can't remember . I received an email on Wednesday from Hulisani Madzivhandlia that he is assisting and will provide feedback . Today is Friday and no communication has been received . I previously has car insurance with FNB , but because of the **** service i received , i am not longer insured with them . i am feeling now that i need to close all my accounts and also perhaps see if i can move my finance because FNB is not what is used to be . There's no service at all . We as customers pay so much banking fees and for what , because it clearly shows only for people to be employed and not provide a service.
