No Finance Cars refuses to pay my spotters fee

In April this year I referred a client to No Finance Cars. The salesmanship referred the client to another salesman. The client made his purchase. I completed a spotters fee form and sent it thro. To date I have not been paid. They very freely advertise their spotters fee on their website but when it comes to paying us R1000 for a referral when they makes Thousands on a deal, they simply refuse. And the reason for non payment is because their staff did not capture my spotters fee on their system. Ive been following up since May 2022 and i have proof. But now one of the managers Lindy says it's over 6 months so I cannot be paid. The other manager Mahomed doesn't even bother to reply to messages. Pathetic company and I will never refer clients to them again
