You need to post the Permalink to the Amazon review (don't know if this is what you posted). Feel free to post the link here for us to verify the Permalink.
If your review has been accepted, your PowerUser page for the item should show "Reviewed" if the review was accepted/validated by Anker. If it does show "Reviewed", it could just be that there are no samples yet available to you to review. In this case, just wait it out.
For what it's worth, I've found that upon submitting my Amazon Permalink, the "Status" will change to "Reviewed" pretty quickly...within 10 minutes. But that's just my experience.
It could be that Anker is a bit behind due to the holidays...maybe contact them at firstname.lastname@example.org to verify that they have verified your review and it's link.
Or they may just contact you here in the forums.
