I saw I had a missed call and saw from the area code it was a Seattle based number. I googled it and saw it was a telemarketer. I decided to call it, to see what would happen. A machine picked up and gave me the option to be put on the company's Do Not Call List. I just had to confirm the number that called me, put in the number I don't want them to call, confirm it and it was done. Now I just have to wait 72 hours for it to take effect.
