Just got off the phone with Canadian Centurion card center. The rep didn't know about the 50K offer but he told me that as of recently, all Canadian Centurion cardholders have been comped HH Diamond instead of HH Gold. They haven't updated their website yet. He will get back to me about the 50K HH points.
Because of FT, I checked my HH account online and found out that I became HH Diamond but didn't get the 50K bonus. I haven't stayed at a Hilton property for over 1 year.
So this is a benefit improvement (or reinstatement
).
