Disgusting poor service from capitec Carlton Centre

I am disgusted by the service I got from Capitec in Carlton Centre, from walking in asking to deposit money was told to go outside and make a deposit when i said that is not what i want to do they hesitated on giving me a number. I then sit and wait for assistance and when my number is called im told " bowukuphi all this time sibizana number yakho sisiza omunye umuntu manje" translation where have you been while we called your number we serving someone else now. At that moment my number is still on the caller board and when i told the lady that is no way to talk to me because the minute i heard my number I stood up and there was someone in front of me the other teller jumped in by the name of Lesego and said "vele bowukuphi coz leyo number was called hai suka mxm" I was taken aback by this behaviour coz my number is still on the board so i got so upset and asked her why are you even talking because I was not even talking to you and this is bad customer service and for you to even talk to me like that is baffling and act like you at a cash and carry while you at a bank. I asked for a manager she was no where to be found. I am annoyed and frustrated and feel not clvalued as a client of capitec...
