Green candy challenge

Hello. I noticed a lot of people were having issues with the green candy challenge. After receiving the correct amount of gold bars and the one hammer for the respective two levels, I didn't think I would be one of them. 

However, after spending a long time collecting green candies for the third and final prize, I was only rewarded with ten more gold bars and none of the other boosters. 

Adter after scouring the internet and this page in particular, I discovered tha I must post a question here and then have my account credited with the correct boosters. 

How long do I have to wait to be rewarded? And will I get anything else for the inconvenience? 

Thank you. Maria x
