Bad service at Fnb Cresta, from teller to manager who does not see the need to show face to clients/customers

Fnb Cresta mall they don't know how to service customers. I went there on Monday the 11th as I wanted to deposit R5 coins and 10 Rands. I separated my money into plastic bags and bundled them into 500 Rands each plastic. 1. The teller told me that they no longer exchange cash, they need to deposit it into your account and charge you a certain amount. 2. When I thought I can stomach that, he then told me that they can't accept the money the way a packed it as I need to recount it and put it into bank plastic bags. Told him the money is already calculated its just for him to obviously double check, he said no. I then I asked him to call his manager, he went to the manager who did not see the importance of showing his/her face to me but only told the teller to tell me that they will take the money but I will need to separate the 1 bag that has fixed 5rands coins, I asked him why doesn't he do it....he told me that I will need to do it myself. I then decided to just take my money and leave, the teller went back the manager to advise that I'm leaving and again he/she did not bother to come and find out why am I leaving. This clearly shows that, why must we expect to get proper service of junior staff while their senior does not know the importance of a client? No wonder why people are leaving Fnb and go bank with other banks, no service at all. What's the point of having tellers who won't rearrange the money as they know how it supposed to be banked and expect you a client to do it? Why don't we have robots once cause there is no need to have them anymore. It's like going to buy groceries and expected to scan your own grocery,, which does not make sense....FNB Cresta, horrible service
