Continually get phone calls from these people but they never leave a number. I don't answer because I'm not certain who they are. If it's a telemarketer then I'm afraid that they'll never stop and "share" my number with other folks. Even though I've signed up for the DONOT CALL list I'm fearful that ny answering I've given tacit approval for them to communicate with me. If it's anyone else they can kiss my keister because I don't answer the phone if I don't know the number.
