Samsung S8 - Free 256Gb SD Card ****

<p>I recently purchased a Samsung Galaxy S8 from MTN and was told I would get a free 256Gb SD Card after using the Smasung Rewards app... the rewards app doesnt list the free SD card, Samsung live support can't help and the company managing the rewards app doesnt seem to respond to any support emails...</p> <p>Are MTN/Samsung just hoping no one wants to claim this?</p>
