I received 2 calls March 10, 2008. I did not answer. I have caller-ID. Four calls March 11, 2008; the third of which I answered. Foreign caller, perhaps from India?, sounded like in a room of callers. Very hard to understand. Mentioned "card", "U. S. Citizen", knew my name. It sounded like a fund-raising call. When I said "We are not interested" and started to hang up he raised his voice and said "I'm not trying to sell you anything!". Two calls March 13, the last of which was answered by another member of household. The caller was told not to call again or he would be prosecuted.
