False Promise and No accountability

Placed a pre-order for the Galaxy S9 plus with MTN on the 5th of March 2018. The pre-order included a gear fit 2 pro fitness tracker and 6 months mobile care redeemable in the Samsung rewards app. After numerous mess ups at MTN I finally received my device yesterday but there is no option to redeem my fit 2 pro or mobile care. MTN told me to speak to Samsung, Samsung said I must speak to MTN. You get how this cycle works. I won't accept that "we are out of stock" because I have proof when I app**** and it is not my fault that MTN kept messing up my application.
