14th Avenue FNB Service is DISGUSTING- LACK OF SERVICE

I reported that I tried to withdraw money on 01 November from an ATM when the power went out.Needless to say no money,no receipt. I then went in the FNB branch at Checkers 14th Avenue to enquire as what I had to do.Firstly they said that I could do it at the the ATM which I did,only to have to go back in the afternoon to fill out a dispute form. Both times I was informed 4-7 working days. I have been there on numerous occassions since then only to be informed that they received an email stating that their is a backlog and I just have to wait.I dont see as to why I should have to keep on going there at least 3 times a week after I have left them my number to contact me give me feed back. It seems to be a case of it's not there money so why should we actually do what we are supposed to do and help OUR clients out. This has got to be the worst service I have ever had with FNB
