Samsung Galaxy S7 Gear VR

I did an MTN online application on the 15 March for this particular phone, with the sole purpose of the Gear VR seeing that the marketing material was that pre-bookings done by the 20 March will include the Gear VR - reference nr: ***0. A week later I then followed up my application seeing that no one from MTN had contacted me as they had promised to do on their confirmation email for my online application. I was then assisted by one of their Sales agent, whom informed me that should my application be successful, I will get an approval sms from MTN. I then received this approval sms together with a notification sms that my phone will be delivered on the 30 March as I had noted at application stage. I received my device as promised on the 30 March, but I now can't redeem my Gear. When I enquired about this from the Samsung rewards team, I got informed that the promotion was closed on the 20 March! What now MTN - I pre-booked this phone prior to the 20 March and as per you marketing material, the Gear VR was still then inclusive with the phone. What now MTN??? What now???
