Stinking bad attitude

I am a first time account holder and as it is my first i had to ask questions to the shop assistance regarding what is it i am signing for and how does the account work...The guy by the name of Thabo at the WESTGATE sportscene store was so rude o me and said he will not answer such questions cause he was not trained to answer such questions and if i wanna do anything about it, then it i should go ahead cause he's not scared. I then asked him why is he being rude to me? he just kept of talking to other employees and not listening to me...I was so angry that i even asked him to just cancel the account but the guy by the name of Nhlanhla had to intervene cause he saw how angry i was......This guy Thabo maybe he needs to undergo another training if ever he did get one at first when he started working in retail....I was so angry, shaking and didn't believe how could one treat another person like this let along a customer like that, by saying "do what you wanna do i don't care" I hope this matter will be resolved because i am so sky rocket angry. Thanks
