Has called multiple times.  Leaves no message.  My general rule of thumb is:  No name on caller ID--no answer.

These numb nuts call every couple of days; always between 8-9 pm - I never answer and there is never a message left - so therefore can't be of any importance!!!

More calls from scam artists using numbers from the Winnebego County area in Illinois. Comes up on caller ID as "IMC". Other scammer numbers related to this are 779-203-9879 and 779-203-9924, where they claim to be Verizon wanting credit card or bank account info claiming you owe money, or some other similar scam

This number calls me every day - sometimes more than once.  I do not answer - sometimes I lift receiver to cut it off because of the constant ringing.  The Caller ID says IMC

I have the number blocked, but my phone notifies me when they call.  They've tried to call a couple of times per day.
