I started making payments on a medical bill that went to collections while I was waiting for a hardship waiver from the provider. I made 3 payments to IC Systems and in June, 2008, their online payment screen indicated my balance due was -0-. In Feb. 2009, they started with the harrassment and ignored all info I sent in dispute - including the website page indicating a -0- balance. In July, 2009, they doubled my debt from $7, 193 to $14, 870.
