I answered before I checked this website. It was a computer voice that just said "goodbye". I thought it was funny. Now I know not to answer this call.
Thanks to everyone for posting!
2nd call today from the credit card scammers. OF course it is a different number and area than the 1st call. Have called our house probably at least a 1000 times by now, and I still have to wonder who is keeping them in "business". Many different scams are being run by the same group of people.
