Caller ID says Mount Vernon, OH.  Left no message.  I get at least one call every day, usually between the same hours.  Every day, the call has a different caller ID and usually does not leave a message, but sometimes, they leave one that says it is of utmost importance that I call them back immediately.  I think this is just one of several spoofed numbers that all come from the same scammer.  All calls seem to quit for a week or two and then start up again, every day.  This pattern has been happening for years.  Or I get three calls a day from different numbers all within about two hours, which continues for several days, and then all calls cease again for several days, which has also been going on for years.  Believe me--no consequences come from ignoring these calls.
