Really dissapointed

I'm really disappointed I bought a car from Fouche motors Renault Clio 2015 expression April this year I was very happy as it was my first car , six months later I experience problems with vehicle as it was not moving , went to them to explain the problem , Mahommed guy who pretended to assist told me to bring the vehicle I had to tow the vehicle to them with an expense of 1500, when the car reaches them he then told me vehicle needs to be towed to Renault woodmead with a price of 1700 that I have to pay, later on about a week he told me he received a quotation from Renault and they need 35000 to fix the car , he told me he was not happy with the price from Renault , he then moved the car where it can be fixed at a cheaper price which was 18000 , whereby I was asked to pay deposit before car can fixed . I had to pay 5000 which I didn't have .
