Car Loan Was Bought Out By Dealership And Then Wrongfully Repossessed

Location: Charlotte NC

Soooo I came out to work this morning to go to work just to find out my car was gone. I called my apartment complex and they said that their tow company hadn't towed it. They called to double check and they said that they for sure hadn't towed it. So I called the police to see if it had been impounded there. No luck. I didn't even think to call my loan institution as all of my bills had been on time and paid. The police said it hadn't been impounded and asked if I'd like to report it as stolen. I said yes. The police come and ask a bunch of questions. As we were walking out to look at the place I had parked, another tenant walked by. The officer asked if they had seen anything and sure enough...

It was towed by a dealership around 1 AM.

The police officer tries to call them and gets no answer. Then he tells me "you know what? I will go down there and ask. I'll call and let you know what happens." And he does. He goes down there and they tell him that it's been repossessed due to a payment issue. I tell the cop that it's crazy since I have all of the statements (bank and loan statements) saying that I have paid. My payment for this month isn't even due yet. He just says to call the dealership and see what's going on. I do just that, except for they won't answer me. And I can't even get down there to talk to them in person. What do I do?

Edit to add information: I called my loan institution and they told me that the dealership had bought out the loan and that they can't do anything else. I brought up my payments and they said that they knew, and that they couldn't do anything about it.
