Did you register your cell phone at www.donotcall.gov? Looks like my mobile number was not registered, Hilton Grand Vacations should not call anyone registered in the federal Do Not Call registry.
They called at 8:35pm PST Wednesday, December 28, 2016. I decided to answer and told the female caller to put me on the do not call list. And she responded with a yes, of course. So we'll see if that works.
