sorry i don't have stock of the prize you have won

I purchased a 12 pack of windhoek draught cans, and their is a competition running where you receive a scratch card and could win a instant prize. My scratch card shown i have won a windhoek wallet the gentlemen next to the cashier said no their is no more wallets and that they should give me a cap, I informed him that I won a cap before and i don't want a cap my scratch card said i have won a cap he said their is nothing he could do while looking the other way without eye contact i told him is not on... He said he doesn't know what to do but still he does not call someone to solve the matter he is flippen rude . They did not take my details to arrange my prise with the supplier no nothing just pointing the cap to me. My point is aside from the rude attitude i won a prize and i expect it, its not about the value. For example it could have been won a tv and then been told sorry no stock left here is a radio. The fact remains i have won my prize and expect it.
