If you have a Android or Apple phone, you can download a call blocker app or call your company to see if they can block the number. Most phone companies can also change your number for free if you tell them you are getting many unwanted or harrasing calls. I have a app that answers and hangs up as soon as this number calls. Hope this helps.
this company calls every day looking for someone who doesn't live here. i keep telling them this and to remove my number from their data base only to get a call again the next day looking for the same people.
