Message is the same as above.. Unable to get anyone to request them to remove my number. I have no idea who it is that is calling. Very annoying. I just don't answer anymore, but they stay on just long enough to 'trigger' my answering machine so that I have to erase the 'non-message' later.
Called my work phone and was unable to catch it before dropping to voicemail. None was left. I called the number back that showed up on the caller id. Got a recording that it was disconnected or no longer in service. Definitely a spoof using a fake call-back number.
