12 deals of Christmas

This is actually apauling. When the Telkom 12 deals of Christmas promotion came out I kept a close eye out for the promotion that included the Samsung gear s3 watch. Finally when I saw it with the Samsung s8 plus I took action and went into the store and purchased the phone. I was told to open the rewards app and burn for the 12 deals of Christmas promotion which I did. I filled in all the required details and received a confirmation email. I then received nothing further and waited around 2 weeks. I then got a bit nervous as I didn't even see an estimated date of arrival. 3 weeks down and I have looked at the progress within the voucher in the app only to see it has been "cancelled as my phone apparently does not qualify for the promotion". How if I bought it on the day of the promotion with a day to spare, when it stated it comes with the watch as well as on a 10 gig data bundle. How has this just been cancelled? I went into Telkom as I figured maybe they didn't validate my claim only for them to tell me to go into Samsung. I go in to Samsung to them too telling me I will most likely need to bring this up with Samsung rewards. Why do you offer an awesome promotion like this only to make it super difficult to get what you paying for? Why do I have keep having to go back and forth without getting a solid answer? I am so tempted to take the phone back and never deal with Telkom again as I feel since they are offering this product they too should ensure that the customer is getting what they are paying for. I am super unhappy about this and will definitely be taking this breach of contract further if I do not get what was advertised and what was payed for.
