I was given a faulty and undrivable car under false pretense after i had raised concerns

my car was spiked where the window, under tray, keys and tires had to be replaced my car had no mechanical faults at the time of the accident, After more than 3 months without a car, renew it gave me back the car with engine and epc light on, i had asked them if they had test driven the car even the errors, and i was told that the car is fine and the engine lights would disappear, in less than 2 km my car was stuck as it was undrivable , i got to the work shop late as they were about to close so couldnt even return my car, its the first time in my life i experience such i was so excited to finally get my car back only to be disappointed and the window module on the drivers door no longer works properly
