Pyramid Used Cars

(With no history of  delinquency) I was late on ONE car note payment and the car was repossessed and auctioned off.
I called to check if it was repossessed the day of.
They said that they sent a "stamped" letter in the mail however I didn't receive a physical copy. (This legally covers them, if they send a letter. Doesn't matter if you get it or not)
I was told by Brian (Last name unknown) that the latest I could pay the fees were on the 10th day of storage. He expressed could pay the late fee and note combined to get the car back. The exact words were "you owe me 785...come in today before 5:00 to pick it up"
Well I had to gather the amount before paying it. This took time.  
When the 10th day came I got out of class late afternoon and called to make the FULL payment. He then told me that the car may have been auctioned. He told me that the auction happens on the 10th day at 9am. (This was not expressed to me before. If it was, I would have made different payment arrangements)
HOWEVER He didn't call me back directly. I actually found out this fact from my co-signer who could be in the office in person at the time. He later walked away from this conversation with the co-signer when questioned about the lack of communication and his contradicting story lines of interactions with me (the buyer)
He didn't explain that in reality the 9th day was "the last day to make a payment" . Which he "wasn't legally responsible to do" as I was told. (You see how shady this sounds?) 
All of my personal belongings in the car were thrown away (jacket, shoes, a few expensive school books)
After some investigation and conversations with others I actually paid more money than I should have for the car anyway.
