Position used for Personal Vendettas.

I have been receiving change from Standard Bank Springbok for the last two years. The teller Tiffy Schmidt refused to give change to me, I then spoke to the manager who explained that they are experiencing attitude problems with the specific teller, and that the matter will be resolved. The manager also explained that we will not have the problem again. Today when I went for change it is again a problem, apparently I do not use the account enough for change and I also have an account with Capitec Bank. Surely I have the right to use as many bank accounts as I see fit, I feel that they have a personal issue with me as it was the exact same teller (Tiffy Schmidt). Every time we use a different teller we have no problems receiving our change. Today the manager refused to see me after going to resolve the matter, She at least phoned me and made a second promise. I am very upset and believe that I will not be moving any further accounts to Standard Bank as the staff use their power as tellers to take out their personal vendettas against Standard Bank Customers.<br> I am not sure what is the problem but am certainly not satisfied with the service.
