FNB centurion mall branch

Utterly disgraceful service from FNB centurion branch! 3weeks since I logged a dispute for a ATM withdraw they made me fill a form and took the proof of failed withdrawal and since the till today not a single feedback has been provide! When we call or msg the FNB support all they say is go to branch they can’t do anything. Now I just get into trouble at work to go and sit inside the branch where they not even bothered to give a small feedback! I need my money back that the ATM failed to dispense
