Game in Centurion mall is unfair

I was an employee at Game in Centurion mall for a week but I was rendered unemployable by Builders Warehouse but i don't blame them for that but my problem is 4 weeks have passed and they have not payed me for the days worked as promised. I have been calling them for the past 4 weeks talking to a ladu named lebo and she always promises to give me feed back and she never does... this week i talked to the store manager and got a call back promise but still nothing, all I need is an update on whats the hold up on my wage, just a simple call but I guess Game only cares about you when you have something to offer them and I don't really want to take legal action but I feel forced to.
