Several times a day, for three weeks, this phone has been calling, without leaving a message.

We beleive this is a phone number used for threats and suspicious letters from a terrorist organization, and we beleive this may be connected with telephone stalking.

THESE PEPOLE DONT STOP CALLING AND HANGING UP THE PHONE!!!

They've been calling for at least 3 weeks now every day multiple times a day.  They never leave a message.  Any ideas how to get rid of them?

Yes,this telemarketing call is from Discover Card.  They are apparently calling people who have some prior business connection with Discover Card. I suspect the best way to get rid of them is to answer the call and ask to be removed from their list.

They don't have anyone to speak to. I called Discover card, canceled my card and demanded they take me off their robo calls.  Today, I received three calls from them. Go to the do not call registry and make a complaint.
