Received a call on my cell...no message

Hilton hotel reservation

Caller did not leave a message. I called the number. It is Hilton. They are soliciting for vacations. They got my number from their rewards program roster. Told them that was not cool. And if they needed to get in touch with me in the future to send an email. NO MORE CALLS.

somehow they got my cell number...    they did not leave message

This is from Hilton Grand vacation...they do not leave a message and when you call back it just says Hilton Grand vacation.
