Received call from KCNC Inc. Man knew my name. I asked what KCNC is. He said a carpet cleaning service trying to make contacts in Las Vegas, was doing a survey. He asked if I shampoo my carpets or have someone else do them. I told him I do not shampoo my carpets. He asked what vacuum cleaners I use. Royal and Kirby. He asked who does the vacuuming. I do. He thanked me and hung up.
