On the contrary, I had an exceptionally positive experience with Hilton's fraud team earlier this year.

My account had been compromised within 12 hours of linking my account to Delta for a co-brand promotion. Hilton automatically shut down my account, notified me, restored my account with a new number, and restored all of my history and points within a 24-hour window.

Others post in this forum indicate that your experience (email only, slow cadence) is SOP.
