Vodacom vodabucks a big time ****

would like to say that Vodabucks is one major ****. Megashakes is a major ****. I spent lots of money to get Vodabucks for shakes and megashakes.You shake to try fill up a puzzle until one block is left ,then things changes. When you do megashakes it gives you the same blocks that you have already unlocked - EVERYTIME, SERIOUSLY!!! 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. Iam sure i will be getting same already opened until it's closing day comes to an end. I feel like they are taking us for a ride because of our loyalty and will to win.Vodabucks is a ****!!!
