Send a message to his alt.  Also post a message as you did before on here stating the terms have been unpaid and that you are giving him 24 hours before you sell the collateral to recover your money.  The issue you have is now that it has been posted that the loan was not paid, someone tagged the account with a (-) remark.  You may want to contact that person who left the (-) and try to get it removed so  you can sell the account.
