Don't want any calls from this #

Enough already, not only calling my cell phone but my home phone.
Have had these calls for several years, and apparently there is no way to get off their list.
I'm not interested in taking a vacation, from companies like this.
Would definitely call it, telemarketing.

why is & how did this person/number obtain when my number is unlisted w/fcc!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
