one ring and then disconnect
called back and usual [***] - this time about my being "rewarded" with a $100 card for visiting one of their "affiliate" websites. Some one must fall for these scumbags otherwise they wouldn't call.
Called my land line. Rang 2 or 3 times. By time I got to phone no one there. Call back revealed it was telemarketer offering $100 gift card or some such. I am on National Do Not Call List.
