Contact Pixel Support.
On your game screen, choose the Settings wheel in the upper corner. Write down your Player ID and then choose the Support button. Do not use the white text box in the center of the screen. Scroll all the way down to the bottom of the page, then choose a category, provide your Player ID, Web-based game vs. Mobile, and problem details.
If you do not see the category options on the SUPPORT page, you'll need to email PIXEL Support at: email@example.com . Be sure to include your Player ID.
