I received a call from this number, who identified themselves as "Bright and Shiny" and they said I won a drawing and they asked what I would like to have cleaned, my tile, carpet, or house and I said my tile. I asked again who they were and what they did and she said they use a "special" machine and they clean carpet and tile and want to show people how this machine works. I then I said I had too much going on and ended the call.
