My Hilton HHonors account was also hacked on 9/29/14, and over 200,000 points were used for a merchandise purchase. I contacted guest services and the points were quickly returned to my account. Unfortunately, they also said that the account information should stay the same, because that would help the fraud protection department track down the culprit. Against my own best judgement, I agreed. Two days later, another 230,000 points are missing from my account. Guess it's time to spend another hour on the phone with guest services!
