You’ll have to fight there are numbers you can call Google lemon laws and stuff like that and you’ll find them. It might take a while but have all your paper work and try to record what people are saying to you get there names times date were at everything. In the mean time I’d get another car because 7k is alot for a car motor unless it’s new. I wouldn’t pay that for a used one and it better come from company’s like Jegs good motor company’s that behind their work.
