Ford Everest worst car ever

I bought a 2018 Ford Everest 2.2TDCI XLS auto. Vehicle has 91,273km's. From the day I bought the vehicle I have been having problems with uneven gear changing, uneven acceleration and t******* sound from the differential when gears change. I took the vehicle to Consolidated auto in Boksburg 3 times and they couldn't find the problem. I then took the vehicle to Casseys Auto Benoni and the foreman said I was the 2nd customer who complained about the acceleration problem. He drove my vehicle and confirmed the problem but said there is nothing that Ford can do to solve the problem. This piece of s**t car is the worst decision I ever made. It's an absolute horrible car to drive because of the constant jerking caused by the uneven acceleration. I want Ford to buy back this piece of s**t car that has problems which Ford can't or won't fix.
