How do I find out how much I owe and who won the bid at the auction?

These people are crooks . Good luck. I now owe uhaul $3000 and they towed it at the apartment complex request however I was outside sitting on the bumper and they kept circling around and literally waited until I walked inside. It was full of several thousands of dollars of mine and my new granddaughters belongings

If the vehicle has already been auctioned off They cannot give you that information. You could wait about a month or two for the paperwork to go through and put a request at the D.M.V for the name and address of the new owner of your old vehicle.
