This phone number dialed me for the second time and it is starting to annoy me.

This is a scam which has nothing to do with Hilton folks!

Too bad their do not call list is a phishing fraud.  Once the sucker is on the list he will receive telemarketing scam calls for the rest of his life.

Yep, got a call from them too on my cell phone. Call back, press 2 after the message, that transfers you to live person and ask to be removed from the list.

No message left.  Not the first time this number has called.
