How do I get my 10000 badge.

Hello, try going back to level 10,000 and clearing it once more. That usually activates the badge :) If you mean in the forum here, you can post a screenshot of your progress at the link below.

If you found my post helpful, please accept it, as it will help me reach my goal. Cheers!

If you make a screenshot post in the thread above, you should receive the badge. Please accept my answer, I would really appreciate it!
