Car problem

I would never in my life recommend Hyundai.1St I had aproblem getting the car registration. Secondly the car broke, it was towed in yesterday and they told me a pipe burst and its a manufacturing fault. Now they are refusing to give me a courtesy car. They tell me it might take a month or more to fix it because they need to order the part...One its their fault...the car is not even one year. Two I should pay AVIS car rental if I need a car....I'm paying my instalments every month and now I should spend more this month because of their fault. I am very frustrated.
