Paying for something I do not have

Purchased a Sony z3 contract with a smart watch from cellucity in pavilion durban two and half months ago. I received my phone and I'm still waiting for stock on the watch. Kept calling and they keep saying there is no stock. Ive escalated the complaint with Vodacom<br> Vodacom has still not gotten back to me after a week. Service from Vodacom and cellucity is pathetic. Either give me my watch that was included in my contract or reduce my contract price. I'm paying almost R500 for this contract!
