I ANSWERED AFTER ABOUT 10 CALL PER DAY FOR OVER A WEEK - THEY SAID THEY WERE FROM TOP CHOICE MARKETING OR MEDIA AND HUNG UP. CALLED BACK TO A MACHINE FROM GOOGLE.
I was receiving up to 8 calls a day from this number and 2 other. I did the SAME work from home stuff as you did, not noticing the MSNBC thing. At least now I know where the calls came from thank you! What I did, is block the number. I can do it through Verizon's website. Check with your carrier to see if they have an option for you to do that. Then call THEM 10 times a day and hang up ;-)
