Got a call from this #. It was a lady declaring that she was with Hilton;and that she wanted to put me up for a stay in Orlando, FL at the new Hilton. Asked for my Visa card #, but I asked that some paperwork be sent to me before I did this. She said that I wouldn't get anything for a few days. She seemed nice, but it felt quite akward.
They will call repeatedly and I don't know if you can stop them. I told them not to call the first time, and it still persists. I just ignore that number now.
