Who called from 6503505950

I have received calls repeatedly from this number.  I have never answered and they do not leave a message.  I am also on the No Call list, so do not know how they got my number.  I see from this website that this number belongs to Fisher Investments, whom I have no interest in .

I'm on the restricted list.  How can they call me?
