Bought this awhile ago from a well known company. The problem is they call me at least once a day. Found others having this problem. They dial a bunch of numbers and the 1st to pick-up gets to talk with a Telemarketer. The rest of the calls are cancelled out and theres just dead air. No one can figure what to do. I already registered with the National Do Not Call List. Hopefully that works. What a pain they are.
