Private investigator Following me

[KREEP]

I had a work accident a while back and ruptured a disc in my back. I had to have surgery and to this day my back still isnt 100%. I went through rehab and am in a lawsuit with the ins. company. They tried to settle and it just was not acceptable and so now I have a P.I. Trying to track me down. I am in no way faking an injury or trying to work while collecting workers comp. pay! I had fucking major back surgery and it didnt fix it 100%percent but I am not sneaking around trying to work nor am i asking for a rediculous amount for a settlement. I just want something to set back incase I have to have another surgery in the future cause those are expensive! Lol. I feel now like I am being harassed! The guy has called my mothers house when I have not lived with her in 15 years and told her he was with ups and that he didnt have my address info....now he is contacting me on facebook and acting like he knows me! WTF???? Has anyone ever had to deal with something like this? Does anyone have any suggestions? I found the guy on Myspace and I now have his phone number ..email addresses and his location ect. What kind of tard private investigator is this guy to not have all his info private. Any one know anything about P.I.s????
