Well all is good thank God, Working and school, As my Probation comes at to a end i went to the Probation dept to speak to my PO, I wanted to see if i could extend my probation because i still owe restitution, the front office lady kind of expland that Probation and collections where separated, She kept paging my PO, But all of a sudden someone had a seizure and i rush to help the gentlemen, ambulance arrive and clear the building, i since been trying to get ahold of my PO but no reply i feel left out lol But thats my ? if my probation is over thats it, just finish paying of restitution? I planned to go back to court my employer kept like 4 grand unpaid wages, vacation time
