MTN not pulling their weight

I recently took a contract with MTN and one of the benefits would be a fit bit pro. I was told that Samsung rewards will deliver this to me. this was in August. The store did the claim for me on some app and said that I would be contacted when they deliver to confirm the address and time of delivery. 2 months later and nothing was delivered and I have not received any calls either. Or missed any calls for that matter. When querying this with the MTN store I was told to email Samsung rewards and follow up. The only send me a list from the delivery company I presume. But that does not mean much to me. I was never called so most probably no one is home. I have emailed them back with these concerns but they are now no longer replying to my emails. I am told that MTN cannot assist as this is a Samsung rewards thing. But how is this possible when I pay MTN every month for this contract. MTN should not offer such deals when they just pull up there shoulders when the terms are not met.... This is NOT acceptable. I need this sorted ASAP as you get your money monthly on time
