Not answering the phone makes XMDC look like garbage. There is no evidence that Lisenby is currently working on anything that will benefit shareholders. For 2+ years, Lisenby spewed about all he was going to accomplish with the Bioharp. That of course turned out to be complete garbage. Maybe another ripoff is being planned, but besides that one can assume, with zero evidence, that nothing positive is being worked on for shareholders.
imo
