extremely bad service

avoid this dealership, i called and asked if they work with spotters and they said yes, i referred a client who bought a 2009 ford ranger , as soon as the deal went through they kept quite and i only found out from the client after he took delivery of the car, the person i dealt with pretendent to not remember me until i sent screenshots, and then tells me now they no longer pay spotters after deal has been concluded, now the client wants to change ownership papers and is un able to because they dont want to sent the papers and when he calls they avoid him and hang up they did the same today when i tried to find out what is the delay and the salesperson who sold the car blocked my number and doesn't respond when the client call, client is based in Limpopo and cant change ownership
