Summer Shack, Vodabucks **** that can change loyal customers

Good day, I have been shacking my damn hand off, with having all the puzzles on 1 piece left from 23rd of December, obviously I will then be spending extra money to get more Vodabucks, yet every single piece I have received has been a duplicate, this is totally nonsens, wanting to spend more money, I could off just bought the prizes myself, without trying to win it on a money making ****, I believe every one is loyal customers towards Vodacom, but dont make extra money out of us, if you dont feel the need to reward us
