Vodacom unable to honour advertised deal!

I upgraded on 28 Dec 2018. The deal was a Samsung Galaxy S9+ with a Samsung Galaxy Smart watch. The watch wasn't available so the deal was on backorder and I had to wait. That is not the problem. I have been phoning quite regularly for an update on the expected date of delivery for the watch. Last week they told me I would get it by the end of this week. Today when I phoned, I was told that the phone I ordered has been discontinued and they don't know about the watch? Last week there was no mention about the discontinuation? When asked if Vodacom was going to inform me about the discontinuation, the lady just said that the consultant with whom I took out the contract was suppose to tell me. I recorded the whole conversation when I upgraded because out of previous experience I knew that something would probably go wrong again. I would like this sorted and know when the deal I signed up will be delivered to me please.
