They left a message and said if I didn't call them back I would be arrested as Rev Can had filed suit against me.  I called them back because I knew it was a scam and wanted them to know that I knew.  I work in a law office so know how litigation works and when I told them this, what do ya know, they hung up. lol   This is not the first call I have gotten of this type, and I expect it won't be the last.
