Spotter Fee was never paid

AUTOHAUS Select Centurion NEVER send a client there, first the salesman will tell you for every client you will get R2 000 spotter fee, After your client take delivery you will hear stories from salesman then the manager

I drove from Pretoria to Soweto fetching a client, the client bought a Tiguan cash after I was NEVER paid my spotter fee, everyday it was a different story. 30 days later I still haven't received my money. I'm a spotter that's how I make a living so when a big company fail to pay me what must I do? The salesman who keeps lying saying my money will be paid for over a month now, His name is Lucky Mosia
