MTN partners with Samsung who is unable to deliver on popular contract deals

I purchased an MTN contract that came with a smart watch and earbuds from Samsung. Once I had signed up for the contract with MTN, I was informed I had to apply for the earbuds and watch that came "with" the contract from Samsung. I was emailed by Samsung that my claim was successful on 14 October and told that it would be fulfilled within 7 to 14 working days. It has now been 27 working days and more than a calendar month and still no earbuds or smart watch. The courier called me from Bloemfontein with my package and was very surprised to learn that I was based in Johannesburg. The last entry regarding my delivery on the courier's - Skynet's - website is on 7 November. It is now 20 November. When I try to follow up with Samsung, they keep telling me that there's a terrible backlog of these orders. They have also told me I was "lucky" to get a delivery date at all (to bloemfontein), and that there's nothing that can be done as the orders are sent through to the courier in batches. They are now ignoring my repeated emails. There is absolutely no will to solve the problem, no accountability, no willingness to hold their courier accountable for sending the package to Bloemfontein, and still no earbuds and smart watch. While it is clearly Samsung that is failing to deliver on the agreement, MTN is also taking no accountability for the fact that their deal fulfillment partner is failing to deliver on a deal advertised by them. I am now receiving usage invoices for a deal I have taken, that has not been fulfilled. I selected that particular deal because of the products that came bundled with it and I do not yet have those products. I am now feeling very negative towards both MTN and Samsung. I have spoken to MTN once or twice to try to resolve the issue - they respond to tweets and the person from the original shop where I took the contract has called and tried to resolve, but they clearly are not able to influence the shocking service offered by Samsung in any way.
