FORD WATERFALL - WHAT A DISAPPOINTMENT!

We purchased a Ford Ranger from Halfway Ford Waterfall in December 2024. From the time we took delivery of the vehicle there were issues. The right front light was not working, brake light was not functioning, right indicator was not functional and many other issues including worn Tyres, brake lights not working and a non-existent suspension which is very dangerous. I brought this to Halfway Ford's attention. Fast forward to March 2024 and we are still having vehicle issues. The used vehicle sales manager Clinton Willis is quite rude and has no customer service skills whatsoever. He shouts at customers and is not interested in assisting. I have escalated this matter to Chilton who the dealer principal but have received no response. I have also let Ford SA know but have had no response either. Can someone assist us with getting assistance from this dealer? We advised that we would be happy rto swap the vehicle for another that is in working order or cancelling the deal altogether. Please HELP!
