You should be at level 5 or higher in your game to get an opportunity to construct your own Wonder of the World on the island!
In case you don't have quests from tourists to get the items while participating in the offer, check whether:
1. Time on your device is set correctly.
2. You are not restricted for cheating.
After that reboot the game and check if everything works. In case it doesn't help, and you are still experiencing the issue, contact our Support Team for the purposes of further assistance.
