Vodacom summer shake ****

Been a loyal customer to vodacom for years, recently heard abt the summer shake game downloaded the Vodacom App to play the summer shake game with kids, however we win the daily mini prizes such as data and coupons. However yesterday my puzzle pieces were all semi complete with one additional piece needed to win the prizes. So we had loaded more airtime, and the Voda shake goals to play to win ( because that's the goal of the game right, u keep playing till u win) to our surprise, vodacom gave us the same repeated puzzle pieces over 30 times, it sent us a message saying error and took away some Voda bucks so we couldn't play more. We Play for the thrill and obviously to win the prizes mentioned but how can someone be playing for so long and just need one more puzzle piece for each prize and never win... Very fishy, scandalous and seems like a huge **** to get ppl purchase more data, airtime and giving them false hope... We decided to tell our friends aswell to stop playing the game bcs it's not worth ur time if u not going to win.
