I recently stayed 4 nights at the Millenium Hilton in Seoul on the company's corporate rate, and Hilton Honors claims that as I was on a 3rd party rate my stay did not qualify for points or stay credit. They gave me a courtesy 1500 points, but haven't replied to my counter query that I was on a corporate rate and had paid the hotel directly.

Is this new? It's been a while since I've stayed at a Hilton, and the first time I've encountered this when staying at a hotel using corporate rates. I tried to search the archives but didn't find anything on this.
