I am at my wit's end. I have been trying unsuccessfully to contact Dr. Pressman and Plasmafire through emails (multiple) and phone calls (multiple). I sent in my Plasmafire ozone generator nearly a year ago. The last time I heard from Dr. Pressman was April, 2008 when he said he was waiting for parts and my ozone generator or a new one would be sent in two week's time. Nothing. Now, I can't even get so much as an email back. Meanwhile, my father who battled cancer successfully with ozone treatments has been without ozone for the entire time the Pressman has had my machine. Apparently, Dr. Pressman did NOT take the hippocratic oath. I know Dr. Pressman's alternative research is excellent, but his business acumen stinks. My next step is to contact a lawyer in his area.
