Bad service

I went to first national Bank in festival Mall Kempton park.it was my first time i recieved a cheque from a client, Because i have a business account there,so I went for help.i met a guy called DUMISANE don't remember his surname but I do remember how he humiliated and insulted me.when I asked for a manager he just sent me to one of the hostess or she was a consultant am not sure and said she was the manager.she also participated in That cherade of making me a fool.i don't know if FNB do they send their staff to customer care training or they just hire all the Tom ****'s and harris.i wasn't happy at all.
