You literally admitted to your rule breaks.. and knowingly broke rules as well as leaving to avoid a punishment, and that worked well.
NLR counts for the district as well as your past life, meaning you can't go back to get your car.
As for the false demote and LTAP, its perfectly valid.

Both the warn and ban are valid, and thus will remain so.
Wait out your ban and come back after reading the rules.
