This is the Hilton Grand Vacations Club (HGVC) or someone impersonating them. Probably trying to sell a timeshare or something. Even though I am a Hilton Honors member, I put them on call block
Be advised that a scam has been prevalent in Ohio where the caller asks if you can hear them. When you say "yes" it is recorded and used to show approval for some bogus charge on your phone bill or possibly a credit card.
Have gotten 2 "hang up" calls from this number in the last 2 days, both around 7:30 p.m.. I have stayed at a Hilton-related hotel before but I do not appreciate "hang-ups"!! I am blocking this call.
