Bought a 2015 Ford Kuga 2

Bought a 2015 Ford Kuga 2.0 TDCI AWD AUTO, had problems with the car and it was sent back for repairs, it took them almost 2 month and qhen the car returned almost none of the problems were fixed and even worse the broke clips on the bumber and fog lamps as wel as cracked the radio faceplate also drove more than 1000km with the vehicle, because the problems were not fixed it went back and they accused me of breaking the clips when it was them, never in my life have I ever had such a bad service, I am currently trying to cancel the deal and trying to get my money back that I already paid on a vehicle I only had for 2 weeks in 3 months
