Same caller: up to 4 calls per day, usually on a week day. Calls by a human operator tell us what we have won a mega millions sweepstakes. Then the caller tells us we must send them a cash payment (or Visa card number) to pay taxes, administration, or handling charges. This has been happening for 6 months. We now let the message machine take the calls. All the calls ! How can we stop these harassing calls? ----Lawrence Hughston, Sacramento, CA
