Who called from 4253682810

receive call from unknown name 3/28/08

I receive these annoying hangups from this company all the time.  How do we get this stopped?

This number comes up on the caller ID as res marketing.  They left a message to call a toll free number 866 366 0388 and claimed to be a representative from my existing time share company.  My actual timeshare company reports that they have no affiliation with this so-called impostor.
