Arrogant manager / poor service

Went to do a "buy back" on my Xbox one. After waiting 45 minutes to be seen, a man by the name of Simphiwe calls me up. I explain its buy back and how much I need, he starts pressing on the body and makes a small crack then turns to me and says he can't offer me much because it's broken. He takes the console into the store for someone else to test. They end up installing a completely new game on my console leaving me standing there for 40 minutes while they testing. Eventually he calls me to go see the console and it shows I must delete something because they want to load 100gig game on there. He walks away. After we test the console, I find out he's the manager of Grassy Park Cash Crusaders and he's busy sitting in the office with a female employee watching something funny.

He couldn't be bothered with serving me. At this point I'm at the store for 2 hours. He does not come back to me and sends someone else to help me and tells the buyer he decided to approve the cash amount less than what we agreed when this initial transaction happened.

Now it could be many things but he didn't ask my name. Not look at me directly, But it seems racially motivated and completely unacceptable. He has poor customer skills and is not controlling the store well at all.

The whole experience was pathetic, especially considering I have done this process before at that store and when dealing with other consultants, it has been a much better experience.
