We continually get calls from this number,  have no idea who it is.  they never leave a message and all it says on the caller ID is UNASSIGNED.    DUH,   like we would answer to these calls!!   We are sick of them,  we are on the do not call list,  but that is worthless.   How would these idiots like to get calls early in the mornings or late at night??   Some people do have to go to work!
