Bad customer service experience

I bought a car in May within a week encountered problems were response was very poor form the consultant when loggin the complaint, I drove in 3 permits without registration,with a broken key they couldn't help as well in resolving that matter.till today m having problems were by it went for the third service and no communication from the dealer and when l do a follow up no positive respond I recieve.I wouldn't recommend anyone to this dealer since there' poor customer service and no respect for customers.
