STENOV48, we completely understand your concern with receiving unwanted calls. We want to do everything we can to help. May we ask if you know who this person is and if you have any other way of contacting them?
You do have an option to block numbers from calling and texting you here: http://vz.to/2rlzMhy as well as the option to change your number online in more severe cases. You can learn how to change your number here: http://vz.to/1gqRgzg
