Calls every couple of days-leave no message. So last night I answered, told them I am on the do not call list. They called this morning again. Guess I'll report them. Definately a scam. While I was explaining that I was on the do not call list, they kept asking over my voice for a Mr._____-trying to ignore me. I don't think Hilton would accept this behavior. I will call them toay and complain. Maybe they can get this hoax to stop.
