Incorrect promotion???

I took out a new cellphone contract on 28/05/2022 at the Tygervallet branch of MTN. The Oppo rep, Michanne, registered me on the Oppo app to get the smart watch, as this was part of the promotion.

I got a call from Naslie from Oppo on 10/06/2022 to say that the watch will be delivered to me within 2 weeks. Today is the 14th of July and I still don't have a watch.

What upsets me, is that the only person that seems to care if I get the watch, is the MTN consultant Matebe. She says that they have stock of the watches at the store, but that it is for purchasing. Is there no way that she can book this watch out to me and you just replace/ refund the watch to them?

I contacted the Oppo support centre via their website and was told the following:

Kindly note that OPPO watch free is only available in case you purchased the OPPO Reno 7 and there is no watches for purchasing in south Africa currently and in this situation that you are going through as you purchased OPPO Find X5 Lite and they told you that you will get a smart watch for free as it's a part of the promotion, so we are really sorry but you will need to refer back to them as it is out of our scope.

So firstly I am being pushed around by Oppo and secondly, it seems that I have been misled
