I bought used car in...

I bought used car in December and the car suddenly stopped and didn’t want to move , I am currently dealing with the dealership and have been requesting for documents which they are not providing me and some of the documents are looking *****ulent, and yes I even requested the dealership to provide me with a proof that shows that the car was serviced before leaving the dealership and same is not provided and I was told by the manager himself and the agent that they are not the ones who services the car but the other party and whereby the other party made it clear that everything is to be done by the dealership, I so regret myself buying my car from this dealer and yet they refuse to give me all the original documents of the car stating that same is obtained at the traffic department because they do not have.
