One person called by likely spoofed number (Indian-type accent) saying that I was selected as a winner of a Hilton rewards stay. I didn’t think it was real but selected "1" to see what they were trying to get at. I did not and would not give any of my information. Not my name or anything although they did ask. Transferred to another person, also Indian-type accent and I questioned where they got my information from, and the woman talked around my question, referring to the sponsor. I questioned who their sponsor was, and she rattled off that it could be Marriot, Travelocity, etc. She finally sensed my skepticism and hung up on me. Never got to the point of asking for any information besides my name.
