Vodacom Shake Off a ****

Vodacom Shake Off is a ****.Talk about puzzle pieces that wont reveal because vodacom doesnt want people to win prizes already shown.For 5 consecutive times circles I have shook off till I was let with one puzzle piece on each price but vodacom will keep on saying you have already opened this puzzle piece until the closing date.You wont win anything until the next closing date.Today all my pieces are left with one piece to win a prize including a mini cooper, money ,appliances etc...but everytime I shake it says I have already collected the piece.They are realy ******** us and misleading us into believing nothing.
