Discovery Medical Aid Being Unfair

<p>I have been on Discovery Classic Comprehensive Plan since January 2016 with all my children there. My wife unfortunately that I have just finished paying Lobola for, was on Discovery Priority Classic paying it on her own. After paying lobola I decided to take my wife on my own plan, but Discovery is telling me they can't put her on my plan as it is an upgrade for her, but if she was on any other Medical Aid they would gladly add her on my plan, I honestly don't see any rational in this . We sent the forms to get her added at the end of August 2016 at the same time cancelling her Priority Classic Plan effective 30 September 2016. They never communicated and only started following up when I called on the 3 October 2016, which means she is currently not covered. </p> <p> </p> <p>What should I do, please help. </p>
