Well, you have posted them here which is good.... but have you posted them and your story on Abstractor Watchdog?  Have you posted them on your Registry bulleting boards, told your fellow abstractors... posted them on your local abstractor network.... have you warned everyone that you can and made it more difficult for them to find someone?  Have you told them what you will have to do with out prompt payment?  If none of it works then you will have to bite the bullet and consider yourself smarter.... they obviously are not going to pay you or anyone.  It's what we did more then a year ago,  then were paid and then they had the guts to call us a month later and ask for a "reduced fee" for volume..... I hung up laughing :-)
