We keep getting calls from this number that are of a debt collection nature for someone who doesn't live at this address.  They say, "We are looking for so and so.  If you are not who we're looking for, hang up or we will assume we got the right person."  Well, how the heck are you supposed to be able to inform them they have a wrong number then?  They ring our house multiple times per week and we wish they'd stop!
