DO NOT ANSWER / CALL BACK. Doing this just confirms a working number and invites more calls. If calling your cell, add this number, or any other number, to your contact list and silence all ringers or tones. delete missed calls later. Helps keep blood pressure low.
Received many calls from this number. I pick up and immediately hang up without saying a word. I don't know who these people are but I agree with most of the people here. However, telemarketers and spammers are only a few of the many types of scumbags that annoy us and sometimes hurt us. I waste as little time on these people as possible. There is almost nothing that can be done to stop these scumbags. The best thing to do is pick up/hang up immediately when you see this number on your caller ID. After a while of this, they'll stop calling your number. I do this with all numbers I don't recognize. I can do this because I only give out our number to people from whom I'll accept calls. Anyone else just gets a hangup or get sent to junk mail. Keeps my blood pressure down.
