They are calling my office phone. I work for a non-profit. They have called 3 times in the last 4 days. Twice after hours so I didn't answer. They do not leave messages.
I figured I would try and call that number back and got an automated message for the Hilton Grand Vacations Promotional Department Response Line. No idea what it is for but from what you are all posting it still seems a bit shady. I didn't go any further other than the first automated message.
I also got a call from this number. I am from Florida and it is the same area code as where I lived but no message was left. Glad I checked it on here before trying to call back.
I too have received numerous calls from this number. And from what I can gather, they are legit and operate as a division of Hilton as Hilton Grand Vacations. If you have stayed at a Hilton brand (i.e. Hampton, Embassy, Doubletree, ect.) property recently or are a Hilton Honors member, that is how they obtained your info and is all legal.
