I've been getting at least one phone call per day (usually 2-3) at all times of day (as late as 9 pm) for the last week or so. Next time I'll answer and tell them to take me off their list.
havent answered one yet. called my cel atleast 10 times in last week. Started in evening so I knew was not business call. but now get them anytime. Now that I know some thing I will answer next time to harrass them.
I doubt that they are associated with Hilton. (1) If you do a reverse check, you'll find that it's a cell phone number. (2) I think that Hilton probably respects the do not call list (and I'm on it).
