Complaint Review: Car Credit City

Hi there, I bought a car from car credit city 6 weeks ago and now its broken down. The transmission jus went out me. I let car credit city know the issue and they told me theres nothing they can do. I told them well I bought the car off your lot so you should do something. I also told them I'm not going to pay for a car I can't drive so they told me they were going too sue me. I bought the car because my last one broke down and I have a baby on the way. Now that this one has broken down I'm all out of options. I dont have $2000 too get the car fixed. I really need some help and I would greatly appreciate it if you could help me.
