I emailed about a missing stay from last week and the HHonors Customer Care replied in about 10 minutes(!)

The agent said the stay posted correctly. I replied stating that the credit and points shown online and on the app don’t reflect that.

I received another reply reply shortly thereafter stating:

”We are aware of the issue and our technical team is working on the resolution. The missing information will be reflected properly on your Hilton Honors account as soon as possible. Please rest assured that this issue is not affecting your Points balance, and the current amount reflected on your account is accurate.”

I disagree with that last sentence, but it may take a day or two to double check.
