Sold me a car with lots of problems

Eish I bought a car the in 2017 November and that car was giving me plenty of problems, some they fixed and a lot they didn't. And they would tell you that they did fix them but they didn't, it's almost 2 years now and I've been struggling with the staring rack for my car, now I can't afford to pay installment and then buy a staring rack. I'm tired of going back there, they're service is disappointing. I regret buying my car there. And also the car had no jack and no spare key.
