NOTE:  They are extremely annoying.  I keep telling them the person they are looking for is not at our phone number and to take our phone number off this person's account.  They say they will.  Minutes later, another phone number (same company calls) and gives the same speech again... looking for this person.  I told the man that if another person from this company (from any of their phone numbers) calls our home again, I'll get the police involved as harrassment.
