Thank you for the responses.
I went to Delaware to get the original title loan but I live in PA.
I was not there during repossession (middle of the night) and I did not receive a certified letter. They said they sent a previous letter, but I never received it, so they sent another letter. They state the original letter was mailed on 11/20 and the 2nd letter was mailed on 12/2. The letter is titled 'Notification Of Our Plan To Sell Property'. It is dated 11/20 and states that they have my vehicle, they will sell it at private sale some time after 12/5, call them to get the exact amount I owe, call or write to get a detailed explanation on how they figured out what I owe them, and to call or write for information about the sale.
They state I cannot get my personal possessions without bringing the key and paying the $75 administrative fee.
