After I contacted Hilton on 1 May 2023; and booked a room, my call was transferred to an associate at the Hilton Grand Vacations (HGV). I was told by HGV staff Magnus that if I listened to a promotional material (aka sales pitch on timeshare), points would be added to my Hilton membership account right away.
Alas, it's 10 May 2023 now; but no points were added. I called up HGV; but my call was passed from one representative to another. The last call was with HGV staff Davara - unfriendly and rude.
To keep the long and very unpleasant call short, HGV does not honor its promise. Lesson learned - stay away from Hilton Grand Vacations!
