Worst service ever

First off all i cant complain about service coz there is no service. From the day we bought my car brand new jeep renagade it just went all bad,waited for my license plate almost 2 months because the sells person forgot about it,and had to pay a fine. Went back and the guy was not working there anymore. Had problems with my radio they just told me my car radio warranty is over,and i find out they were lying to me. I waited 7months for a new radio and still they made a mess to connect my radio now my steering wheel is not working,and my kilometers are flickering. They told me they will come and collect my car,but just again empty promises. First i have to put down 20 thousand for a curtsey car,cause they have to take my car in. So now they make their problem my problem. Its just empty promises,and its the worst service ever....
