VODACOM SHAKEOFF IS A **** & A CON

The vodacom shake off is a **** and is rigged. I have been playing it everyday for months now. I have been receiving puzzle pieces every time i shake. I currently have 5 (five) puzzles which have only 1 piece left since December and everytime I shake I keep winning pieces that I have already received. YET a new puzzle has reset today and I've already won 3 pieces for the new puzzle. Whenever a new puzzle appears you win multiple pieces in 1 day but once theres just a single piece missing you can play it for weeks you wont be able to win. I have spent a lot but since December on airtime. How can I have 5 puzzles missing 1 piece since December and playing every day but I keep winning pieces I've already won but today I win 3 pieces for a new puzzle which loaded today The process is clearly manipulated by VODACOM in order to ensure that we keep buying airtime and playing knowing full well when we about to win they step in and manipulate the process. They are deceiving us and it's just a moneymaking scheme.
