Answer: Hilton should credit you the double points — on the double. Dragging this out for weeks and then offering only a fraction of the award points is completely unacceptable.
It would be bad enough if Hilton was doing this to a tourist. But for someone like you, who spends more nights in a Hilton hotel than at home, it shouldn’t even be necessary to ask twice.
Is Hilton required to credit you for your stay within a certain time? As far as I can tell, no.
The terms and conditions for HHonors, Hilton’s loyalty program, are silent on this issue. (You can read it online here.) It says a lot about what your obligation is to the company. For example, if you don’t earn points in any 12 consecutive months, you could lose everything. But it doesn’t really mention Hilton’s responsibility to you. Specifically, there are no assurances that Hilton will credit you with a hotel stay within a specific period of time.
So by failing to put the points in your account, Hilton wasn’t violating its own terms. But how about reneging on the double points deal and offering just 5,000 points? Again, Hilton gives itself a broad license in its terms to “add, modify, delete or otherwise change any of the rules, procedures, conditions, benefits, Rewards or Reward levels pertaining to the Program at its sole discretion, with or without notice.”
In other words, Hilton did nothing wrong. And it did everything wrong.
You don’t treat a customer like this.
I think this might have gone smoother if you’d taken a moment to compose a short, cordial note and sent it to Hilton. A written request is far more difficult for a travel company to ignore.
I contacted Hilton on your behalf, and it contacted you and explained that the Hilton property where you booked your rooms had experienced a “problem” with posting award points. You’ve been credited with all of your points.
