Yes I just started getting them . No message left . . Looking across the net it seems several others  have as well  but no one as yet has commented as to what the call may be about . So I called them and it seems they are Diversified Consultants Inc based in Florida

spoofing a Colorado phone number  looking for someone who at least in my case has never been attached to my phone number ... a certain Clayton Smith  [ as well as several other names  ] They are a collection agency / debt buyer  that seems to be generating random phone numbers in a desperate attempt to track down delinquent accounts they have purchased for pennies on  the dollar  .

For the record  It is illegal for any legitimate  Debt Collector to spoof phone numbers on caller ID and I will be fling a formal complaint with both my State Attorney General [ Colorado ] as well as the FCC etc . I suggest you and anyone else receiving these calls do the same immediately
