Vodacom shake off rigged

Im so happy to see other ppl complaining about the shake off of vodacom....i should have won big prizes for the past 3 months. But dec was the pits!!!!!...i had 5 prizes on its last puzzle....from the 15th of dec i get sorry you have this puzzle already...this morning i got 3 puzzles and all with the same sms..sorry you already got this...its dusgusting as to how they treat you...i spend hundreds of rands on airtime...this should of been a reward to say Thank you for buying 600.00 airtime a month ..sometimes more....but instead they rig the shake off...so my question is..how stupid do you think we are...or how little do you think of us....the rules are...if you get all the puzzles to a price you win that prize...you ****!!!!!...ITS SUBJECTED TO" WE JUST WANT YOUR MONEY AND PRETENDING TO GIVE YOU BACK FOR YOUR LOYALTY"are any of the winners ever real or are they employed by vodacom...very disappointing
