Woman asked for me by name. I did not answer, but asked her who was calling. She said she was Amanda (I doubt it) and was calling seniors, especially those with back problems. Then she asked if I have back problems. I told her I don't answer questions from callers I don't know. She politely thanked me and hung up. The thing is she spoke very slowly and distinctly, but sounded as if she was trying to hard to enunciate correctly, causing me to believe that she was not in the U.S. When I call the number, I get a fast busy signal.
