Have you tried completely shutting down your game & restarting it?
Have you tried clearing your cache, cookies, history etc? (If you can do this)
If you have your player ID number & game progress registered with either your email address or Facebook account....you could try uninstalling & re-installing.
If you have done everything but you are still having issues....then I suggest that you contact Pixel support directly.
There are 3 different ways to contact PIXEL SUPPORT.
Remember to check your email spam/junk folder for replies
Do NOT send multiple Pixel support tickets in quick succession...otherwise their spambot might eat them
1️⃣ You can contact Pixel support directly through your game settings menu
2️⃣ You can also contact Pixel support directly through this link
Do NOT type in the white search box....scroll down to the categories written in BLUE
3️⃣ You can also send an email to Pixel Support directly through this email address
