Mtn Around SA with Samsung & MTN

You log onto the Samsung Rewards app and register the detail that come with the phone to qualify for a MSC cruise to 2 people. I have done that and received an e-mail saying the IMEI no on the phone is incorrect. IF you press *#06# on any phone the IMEI no comes up. I also took an image from the box with that IMEI number and that image is not accepted. They should not advertise and then send you e-mail that the image or IMEI number is in-correct. What a waste of time.
