Do you have any HHonors status, pitsheel?

If so, you could try the HHonors toll-free telephone number: 1-800-HHONORS.

If you are a Diamond VIP, call the Diamond Desk.

If not, try 1-800-HILTONS.

Additionally, once you report your problem to customer service, fax them a hard copy of your complaint.

I have found this method to be faster than electronic or conventional mail. You get to speak to a live person. I have personally achieved favorable results using these methods in the past.

By the way, for what it's worth, I find that your situation was mishandled, unacceptable, and not up to the standards of Hilton Hotels.
