bad and unproffesional attitude

Went to fnb sosh crossing to increase the limits on my 12 year old daughter's account. On arrival Nakedi who was placed to issued queue cards did not even greet me and the clients before me. He just looked at me and I told him as I was tryinng to buy an electricity with cellphone banking I received a notification that my limits has been reduced for my protection and told him I wanted to increase them. He insisted on seeing the sms and when I told him it was just a notification I received while trying to use cellphone banking, he spoke to be on a high pitched voice, got angry and said that \ or what?
