Global Research International has been calling my home phone up to 5 times a day, morning, noon and night, for over a month. I am on the Do Not Call List. This number comes up on my caller ID: 213-452-6533. Sometimes they call every 10 minutes or so. They have also called after 9:00 pm. I have no idea who they are or what they want. I will not answer my phone because I don't know who they are. They never leave a message. They are VERY annoying. How do I get them to STOP CALLING ME???
