If you also pressed the Claim Button (if you are talking about the Video Snail) or it's about the "Offers" of the Main Menu, please contact the Game Support. The informations for the support, you can find in the game (Main Menu > Help > Contact Support).
Please note, this is a fanbased wiki, the game developers aren't around here very often as they don't administrate the flutter wiki. TO make sure your issue is read by someone, who can fix it, take the way written above.
