I Bought A Car From A Dealership 11 Months Ago And I Still Have Paper Plates And No Loan.

At the end of June ‘2023 I bought a used 2021 equinox from a dealership. I’ve continuously reached out to the manager to asking when my info would be sent into the bank so I can make payments and when my hard plates will come in and she just keeps giving me the run around. I’ve had 4-5 different paper plates. I bought from a dealership back in my home town. In the beginning I was making weekly trips back home because she kept telling me that she would have my plates and never did. Half the time she wouldn’t even be at the dealership. Today, I had the vin information pulled and I found out that the vehicle is still registered in the previous owner’s name. She told me Wednesday that she was overnighting my plates to me. I texted her this morning asking if she sent the plates. No answer. Now I’m a nervous wreck to even drive the car. What if I have an accident? I’m looking for guidance on what my next steps should be. I already filed a complaint with the Texas DMV. At this point I just want to take the car back and get my down payment and trade in value for my old car so I can go to a different dealership and get another car. There are complaints from online from other people that are in the same position I am. Do I take legal action? Where do I begin?
