car sales

I bought a car and it broke down with in the first couple of days. I took it back to them and they did have it fixed. A very short time later it broke down again. I took it back to them. This time they made me pay half. I got it back again. It broke down again. I took it back to them and this time they wanted me to pay the full amount of the cost that was over $500.00. Each time the care broke down it was a major repair. They lied to the BBB and said that they paid for the repairs 3 times,they lent me another car while mine was being repaired, and if I keep my mouth shut that they will think about not hurting my credit rating by turning it in.. One lie after the next with them. Do not trust them.
