Don't care service

I bought a car at InspectaCars Gazina in March and regret it. First of all they sold the car that I was busy to finance first. On the 2nd vehicle the lights was faulty, I ask them to fixt before delivery that was not done. It took them two months to do after delivery. Now after six months I drive a BMW that I must replace all four socks and low controll arm bushes that is totally up. Mohammed feels nothing and Juan is just a hasbeen there that dont answers calls or whats apps. I asked them if they can help me with the low controll arm bushes I will sort out the shocks. But they refuse.
