Vodacom shake it up promotion is a total ****

Vodacom shake it up competition is seriously a ****. I have been playing for more than 2 weeks now and now that I have finally got to a point of almost winning on one of the puzzles I have now been getting duplicate puzzles. I went out of my way to buy airtime and data to get additional vodabucks and guess what all my puzzle pieces are duplicated. So i took the liberty to call through and speak to the vodabucks department yesterday at 18h42 and the gentleman that i spoke to said that this is not right. He then logged a call and till now no one has called back, I have in the interim tried playing more and still duplicated then I called in again and now no one answering in that department aswell the customer care cannot assist. So I honestly think this whole thing is a **** with all the duplicate puzzle pieces by now i would have won the 50k cash prize and the Samsung phone aswell i would have been 1 puzzle piece away from the mini cooper. How can Vodacom be running a promotion this big, advertising on the radio stations and still be robbing us the consumers. Again even publishing here they will probably just send out a response saying someone will contact us which will probably never happen. All I would like to see is them adhering to what they advertise and actually release my puzzle pieces before the puzzle expires on Monday.
