Disgusting service

I'm so disappointed with the level of treatment I received with one of the officials at SMG Durban Central. I spoke to the salesman over the phone about evaluating my car with an aim of selling it and he politely told me that he will not be available at work but I dont need to worry, I must go there and ask for the guy by the name of Fikston or something like that. I went there on black friday, was greeted with a smile and asked what kind of assistance I need. I told them I need to see this person. So the guy called him, he came with an attitude and mumbled something and he went up the stairs completely ignoring me. I sat and waited, assumed that he was sorting out somethings and will come back. Seeing that he wasn't returning, I went to speak to the lady at the reception who phoned him. Oh my God when he came down, he did not look at me and was busy touching his phone, he opened his hand and I had to guess that he needs a key for the car. He then said, where did you park and I told him and he left. He came back after a few minutes and just handed the key back again without saying a word. I thought to myself that let me leave and I will call the sales person on Monday to find out. This guy is disrespectful, I'm not even the kind of person to complain but this was a first for me as I have been going there since 2012 and have never been treated like this. He needs to be cautioned as his behaviour is impacting badly on the whole company.
