I can only help if there is an issue with the quests. There isn't for this game... so it's an issue on the user's end.
About all I can suggest is:
-Make sure you're logged in
-Make sure you're not in incognito mode
-Make sure you have cache and cookies turned on
-Try refreshing the game and see if they award then
-Try disabling ad-block
That would be my general list of troubleshooting advice, for any quest issue where it's a single user having an issue vs the game causing problems. Hope that helps!
