Yes I got "points claimed successfully" message on the page. I also retroclaimed CI and UX which already posted but not AM.
You can try claiming them again.
If you flew on Dec 10, try claiming the flight again on Dec 9, 10 and 11, maybe also 8 and 12.
You will get an error message, but that seems to get things moving.
You may also get the option to send in a manual claim, and in the manual claim form, you can change the date back to the correct one.
Good luck.
