I was getting hassled by one particular debt collector and wanted it to stop. They were calling on my cell phone and while I was at work. I Googled how to do it and came across Mike's site. I downloaded the Collection Blocker letter, printed it out and sent it in, and never heard from those creepy guys again. By the way, all of this was free. I even asked Mike some questions by email and he got right back to me! Amazing service. Would definitely recommend!Anonymous, San Francisco Bay Area
