Maybe its time to level up and try using a collections agency like: http://www.olddebts.com/

Whenever a client seems to be giving me the run around I pay for a simple `Instant Collect` + `Credit Bureau Reporting` (should be around $10-$15) and its amazing how the threat of destroying someones credit can change the scenario ;)

I actually used this strategy to effectively get paid back from a law firm! No lawyer needed.

It might just put you at the top of the list of people to repay.

Not vouching for olddebts here, though I am happy with their service. There are other options.

Definitely don't give up on ANY amount of money.
