Unreliable Ford Everest Platinum 3.0 V6 coupled with bad service from Ford and dealerships

I've bought a Ford Everest Platinum 3.0 V6 a year ago. It now has 34000km on the odometer. At about 5000km they had to replace the stereo speakers. At 32000km the 10 speed gearbox had to be replaced. Now 2000km later the vehicle has electronic issues that shows multiple mal functions on the display. The electronic parts were replaced. In all I was more than 2 weeks without my vehicle. None of the dealers BB Auto in Menlyn and Casseys Auto in Springs could supply me with a courtesy vehicle. I've complained at the dealerships but received a non care attitude from both dealerships. Ford South Africa has not responded to any of my complaints. It's truly the worst service I've ever experienced from any motor company. I now have serious doubts about the reliability of the vehicle. I've asked the dealerships to supply me with an offer to buy back the vehicle and was offered more than R50000 below trade value. A loss of approximately R250000 from new. I shall never buy any Ford vehicle or make use of any of the above mentioned dealerships ever again.
