Still waiting

I upgraded my one number earlier this year. The store was full of promotional items indicating that I will get a new Vodacom Super Rugby jersey with a Red upgrade. I did the upgrade and was told by the person that they do not have a Lions jersey in stock, but she will arrange for me to get one. I never received anything, and about 2 monts later I went back to the shop to enquire. I was told by another male person that their was never such a promotion, and that need proof before he could assist me. I went back today with proof, and was now told that it is not the shops problem, but that I should call customer care to resolve this. This is really frustrating, nobody takes responsibility, and I am driving up and down to resolve a issue created by the specififc Vodacom Shop.
