OK, had this happen to me. 1. Don't make up a witness or do anything illegal. 2. Give the details to your insurance company, but don't bother to claim. 3. As suggested above, appeal to the nicer side of these people. Always be polite (suggest that they may have been "mistaken" rather than call them liars). Give them a genuine quote. 4. Knock on their door and say Hi every time you go to your mates house. They will soon be sick of you. Might weaken their resolve if they get the feeling that they will never get rid of you. Remembering, of course, that if you are always polite and never break the law that they can't do much about you hassling them. 5. Ask your local free legal service about the small claims tribunal (cheaper than trying to sue someone, but same net result) 6. Give this information to the people on your next visit. 7. Never give up. I had to call a guy for 3 months to get $700 out of him that he owed me. I ruined his life and he figured it was easier to pay me to get me to stop. 8. Don't forget to do some amateur detective work. Check their mailbox one day to get their names (OK, that is illegal, but be quick!) or even check the electoral rolls (at the Post Office or a public library?). Getting their names will lead you to their phone numbers! Yet another way to give them the ****s! I have had to chase people a few times for money owed to my side business. I have always got it but sometimes it takes some dedication. It is only an extra 5 mins to your day to hassle these people if you visit your mate (you are already there). Calm and patience - even if you never get the cash, you will hopefully have gotten your money's worth by ruining these bastards lives. After 6 months it is time to give up or start sending pizza deliveries and other pranks around.
