Unacceptable behaviour at We buy cars pietermaritzburg

I was at the Pietermaritzburg branch today at approx 13 45. I have engaged a few retailers froa deal on a Renault duster. New demo and used. On arrival I had to find someone to assist. The gentleman pointed a duster to me and left me unattended. I looked at the car and went back to him for more info. He said I should scan qr code which I went back to do. I then returned to him as no info was displayed whilst he was blowing up balloons. He refused to help me and said he wasn't a salesperson. I then asked him to get me a salesperson. He ignored me and continued blowing balloons with two other employees or we buy cars. I asked his name and he said I must go find out. I said I will have to fone through a complaint and he arrogantly said thank you. I took my fone out to take his Pic and he said he will smash my fone. He proceeded to say he was not my child. In retrospect he had me running at least three times though a warehouse on his instruction. I would like a call from his superior and a formal apology for this ill mannered, I don't care behaviour toward me. Maybe it was a race issue but this is not a healthy retail environment to step into. I did and still do want to purchase a vehicle. I have sold two of my vehicles to we buy cars prior. This is unacceptable behaviour
