Bad service

I made a deposit to a minor account at Nedbank Kanyamazane, so I only realised the following day that I was charged for making the deposit inside the bank and also charged an extra R200 which now exceeded the money I deposited. I went on Tuesday to enquire the guy I found said he didn’t understand why they changed me the R200 I must go call the toll free number which I did when I got home, the lady explained that I should return to the bank since they shouldn’t have charged me this much for a minor and they have to explain. I went back now to the branch where I now found these three rude ladies, the first one said I must open my app since she will charge me if she checks on her side. She also didn’t understand why I was charged that amount but she knows that everything done inside the bank I must be charged so she can get paid. She referred to the next teller now who said I since I had coins I was supposed to go to PEP or KFC asking to change the money, am I not an account holder with them? I left the bank with no proper explanation for why I was charged but did receive bad attitude from these ladies. Bad service the staff that was there before was way friendlier and was willing to assist.
