I have a story to tell... just so you don't have to read the entire thing, the lessons are as follows:
- When you can't find somebody, become a PI. Use the net, particularly search engines, google, copernic, etc. Insert the person's name, variations on the name, their town, State, whatever you know about the person, occupation, wife's name, whatever... not all at same time, but words in combinations which are likely to be rather unique and lead you directly to the right person.
- When you get a lead on where the person might be, follow it by careful conversation phrasing which avoids lying, but leaves implications which will encourage the other person to give you better leads as to finding the person.
- When you actually locate the person, plot a strategy PRIOR to contacting him directly. The strategy should be aimed at providing MAXIMUM embarrassment and exposure to him ... or at least threaten such so that he is motivated to settle up with you.
Now, the story.. which I agree is on a different $ scale than where you are.
My MIL did bookbinding for a fellow, contract was signed, total cost was about $400. Work done, notifications sent monthly to come pick up work and pay, phone number ceased to work, person was unlocatable.
MIL turned it over to me.
I got out computer, browser, search engine, inserted first name, last name, city and state of last known residence.
Quite a few hits... looked at each carefully...used "find" function to locate the name within web page.
One web page was the adult Sunday school schedule for a local church.
Offender was listed as the teacher the next Sunday.
I called Church office, got secretary, inquired how to contact the teacher, by name, because I was interested in the class, wanted to talk to him personally, embarrassed to leave a message. She gave me a number where he might be reached.
I called him... AMAZING...got his answer machine, recording had NOT even been changed, gave prior (now inoperative) phone number, so I knew I had the RIGHT fellow. Left message of interest and desire to attend Sunday school class he would be teaching and pled with him to return my call, left number, never mentioned my MIL name or anything about debt owed.
He returned the call (Friday night) and I verified he would be teaching the class on Sunday, said I really wanted to be there, got all info about time, place, directions, etc....
Then, I laid the trap, asked if he knew my MIL... he stammered, but being caught off guard, admitted he did... I said, good, because I thought he was the fellow who had left a bible to be bound with her almost a year ago and I need to to tell him that she had been carrying his bill without carrying charges for 6 months, but now was charging him $10/month extra for every month he didn't pay for the book...but, I would be willing to do him a big favor...
I'd be glad to bring the bible to Sunday School that Sunday and he could pay me DURING the class. He tried to bargin.... "I'll be by on Monday and pick it up... no need to come down to the class." I was soooo nice....."Oh no, it's no trouble for me to bring it to you on SUNDAY DURING THE CLASS...I CAN BE THERE WHEN CLASS STARTS."
He began to get the message... agreed to come by on Saturday. We agreed on 9:00AM SHARP. Else, I was likely to be gone for the rest of the day and then I'd have to bring it to him on SUNDAY.
He arrived at 9:00, paid $500, was pleasant and left.
My MIL was soooo happy!!
Your search terms, engine, results may suggest a different embarrassment technique, but I hope your results are similar.
Best wishes!
