Ford Everest Persisting Problem (Worst service)

I bought a new Ford Everest Limited Edt in 2015. In 2020 September 27 Sunday when we attempted to depart from our holiday the vehicle made a knocking sound in the engine, the vehicle had plus minus 48000km. Monday the 28th of September I took the vehicle to Action Ford Krugersdorp, and delt with Werner. Ford felt the vehicle was not driving enough and the bearing was not getting enough oil. I did not agree with this, but I am not the expert. Ford could not defiantly determine the problem but told me the vehicle went out of warranty, But Ford first wanted to do a Sub assembly, but there were no stock, instead the replaced the engine, this cost me R61 400, and they would pay the difference. I then received the Ford with the brand new engine, and the Ford struggled to start at times. I then took the vehicle back to Ford, and delt with Werner and the Mechanic and they told me that the Camshaft sensor was lose and the alternator wire was lose, and they repaired these said faults. I then fetched the Ford, and immediately the vehicle were not starting. Ford now thinks it’s the Crankshaft Censor needs to be adjusted, and the vehicle were put on a lift on the 17th of December 2020. My vehicle were in and out to Action Ford and every time Ford tells me that some or other Sensor needs to be replaced after a complete engine were replaced. Also on the 17th of December Ford tells me that one of my battery cells has died and they fitted a new battery, I had to pay R1850. They felt this was the problem, again after a completed engine change was done, and Ford assured me that the problem was resolved. On the 19th of December the vehicle again did not start, but this time it took about 35 min for the vehicle to start, each time it takes longer for the vehicle to start when this problem starts. I am totally disgusted in th e service I have received from Ford. I have been more than patient, and on Fords recommendation replaced, the engine and every other component they so seen fit, in order to resolve a problem that that has up until now not been resolved. I am writing this complaint because I will not spend one more cent on this vehicle, Until Ford SA provided me with a complete report, and pave the way forward.
