False Promotional products!

I took out the new Samsung Galaxy S9+ contract, that is supposedly coming with a 128GB and Dex Pad if you take the S9+ which I suspect is false advertising! Firstly, you don't get it, you have to redeem it on the My Vodacom App, which is strange because it gets advertised as if you get it with the phone but you don't. Once you do it through the Vodacom App, nothing happens. I phoned Vodacom to see if it is still coming as they are going to "deliver" it to me or rather thats what it said on the app once I redeemed it, but I spoke to 5 different people from Vodacom contact Centre and no one had any clue as to what this is. When I tried to explain it to the last person, that works in Online orders, the lady said that I had to have received this in the Vodacom shop after getting the Ref number, as they get the stock with the phones and need the Reference number to give the Card and Dex Pad to me. I drove to Vodacom shop, where I was just shown away again saying that they will deliver??? Which one is it now? it has been 2 weeks since I did this already and still no message to say that they are on it or I will get it in the next "4 weeks" which is what the Vodacom Shop told me. I feel that this is a way for Vodacom to attract more customers with their false advertising.... And I know when I phone back after 4 weeks to follow up on this order Vodacom are going to say that the Promotion is over and that I don't qualify for this anymore?

I also got the R300 discount on any Samsung Product, but to no surprise, all the Vodacom shops that I went to only have the Samsung Pouches / covers available, no chargers or car chargers or anything like that. So you give me a voucher that I can't use and also sell it as a "Special R300 off any Original samsung product" but nothing is in stock? And then the voucher expires in a few days... but I can't buy anything with it?

Not a happy customer at all...
