Product: Vehicle loan or lease

I purchased a used car from XXXX XXXX on XX/XX/XXXX, who not only scammed me, did things illegally, and took advantage of me as a first time buyer. I am someone who has XXXX, and planned on sharing this car with my XXXX  grandmother. They sold me my car with an engine light on which is illegal, and promised me false things. They told me they'd be giving me a new door handle, fixing the engine light, checking out there issues such as my ac, and my breaks. Ever since I got my car I continuously had to bring my car back to be repaired. I got a flat tire not even a week after getting my car and was blamed immediately, and told I must pay for it. While my car was with them for two days I was not contacted whatsoever. As I called I was told they fixed everything. As I got in my car none of the issues had been resolved. Neither did I get my registration yet. When mentioning and begging for it I was told to NOT worry about it. It soon went passed the seven day limit when I still didn't receive it. After having to constantly call them, I was finally given it two weeks late. They told me to come back to get my engine light fixed. I had no sticker for my car, and was forced to get it only for it to get rejected. Something odd I noticed when getting paperwork from that was that the miles on my car 's number was not even near what was written on my purchase contract paperwork. Instead of XXXX, the inspection paper said it was XXXX. The place I went to get my sticker has nothing to do with my dealership. Their paperwork held the truth, and not lies like my own papers from the dealership did. Despite this, I brought the car back one more time hoping they'd finally fix it. Once again, I was lied to by the dealership. I had dropped my car off around XXXX XXXX  and didn't hear a thing. I decided to call back by XXXX XXXX  and they mentioned filing my car up with gas for no reason, and needing me to drive it around. When questioning them, as I didn't understand I was shut down by them. I soon asked about the engine light, only for them to not answer me. I have left my car with them ever since then ( it's almost been two weeks now ) as I'd rather not drive an unsafe car with several problems. I was unable to go back there as I have no way of getting anywhere now without a car. My father sent a family friend, telling them about the false information, and telling them I'd like my money back. Instead, they lied yet again, and said I waited to long which is false. They purposely delayed me multiple times in order for them to get more money from me, and for me to be trapped with this car. As I write this, they continue to harass me, and call my phone. I have been in touch with West Lake Financial which are my loan people. Despite my evidence, and information sent to them, they can not cancel my loan. They keep asking for information, in which the dealership would NEVER give to me, regarding the engine light. Due to this I told them I will not be paying for such a car. I have left it at the dealership and told the loan people that I will not be paying, and that it's already at the dealership for them. I am someone who is young, and haven't established any sort of credit before. Now my credit is going to be ruined, because I refuse to pay a loan for a dangerous car.I have called them everyday, begging for help only for them to dismiss me. I am terrified as, I am suppose to pay on XX/XX/XXXX. I do not know what is going to happen next. Any sort of help you can give me will truly be appreciated. Thank you so, so much!
