Car Problem

I would never recommend......I'm very frustrated with Hyundai Milnerton, they expect me to pay a rental car for a month or more after I took back my car yesterday I bought it in December last year, some pipe in the engine broke and they told me its a manufacturing fault. Why should I spend extra for something that is their fault?? I requested for a courtesy car and they're telling me stories. I don't tell stories when I have to pay my car instalments.....I would understand if I was at fault. The dealer principal is refusing to speak to me.
