After Dana George from Hilton left me the Yelp comment on this review AND emailed me with the note below on May 16th, about a month later I've still not received the points. If this is how they treat their Diamond tiered guests I can't imagine how they treat everyone else...ridiculous.
Dear Mr. Ng,
I received a correspondence from our Hilton Customer Service Center in regards to a copy of your receipt and the credit of your Hilton Hhonors points for your stay from 4/29/12 to 5/4/12. I have emailed you a copy of your hotel receipt on a separate email and I have personally gone in and submitted your points. You should be able to view this credit to your Hhonors account by tomorrow morning. I truly apologize for the confusion and added work this has caused you.
Regards,
Dana George
Assistant General Manager
