Vodabucks is a ****

I would like to say that Vodabucks is a major ****. Megashakes is a major ****. I spent over R300 to get to 200 Vodabucks. You never get to win anything. When you do megashakes it gives you the same blocks that you have already unlocked - EVERYTIME!! I have literally unlocked almost every puzzle but there is always one block left for every prize yet I get the same block everytime of which I have already opened. Vodabucks is a ****!!!
