Hyundai Anton Lembede street and their thieving D.P

So for around 2 months us at Cars, Combovers and Coffee were doing valets for Hyundai on Anton Lembede street. Their account reached an amount of around R9000 at which point their Dealer Principal a Mr Leon Van Eerden said they would need to add us on to their service providers database which would require us sending them some documents (which was done on numerous occasions). Now after owing us the money for over a month and getting no joy out of the dealership I was left with no choice but to get my lawyer involved. He proceeded to call Mr Van Eerden who denied any knowledge of business with us saying he didn’t even know the company existed, this being a man who I handed back invoices and car keys to once vehicles were returned to the dealership. Now I get the run around from the dealership. Is this how you guys operate Hyundai South Africa?
