has called several times in the past 2 weeks, nobody is there when I answer

THese people keep calling all week including Saturday and Sunday and they are looking for someone in debt and we tell them that the person (wrong person, wrong tel number and even wrong State) does not live here and take the number off their list and they say they will but someone else calls back the next day.
What a pain

I am now forwarding all calls to the Police Dept and if all of you do this, I think we can take care of this Company's harassment.

calls and says doing a study for an Ohio university.  Wants ask questions.  We deny them, and have asked to be taken off the list.  They still keep calling back

Leaves no message, caller ID displays 'Cellular call'

Has called several times, leaves no message.  Caller ID "LSAN DA 01,CA"

Asked for a contribution.
