********** competition

this summer unlock is a *****, they tell you that you have won coupons or vouchers but they are invalid. I was also told that I had won flip flops, earphones and a speaker which they never delivered, I logged a call and given a reference number but the call was closed a few days later, I then called again but guess what they can't find my reference number but they will "get back to me". I can't believe in this day and age companies still have competitions withou.t prizes. Vodacom is such a big company to be running a ********** competition
