Discovery health, worst experience ever

We recently moved to discovery health to join my husband's medical aid. After 3 months were told that we will be removed from medical aid because of some non disclosure, which was proved to be incorrect. So we were actually removed and Informed that we would be reinstated starting 1 October, all of a sudden we now have to be on a 3 months waiting period, however when I called their number to confirm that we are now added to the medical aid, I was told that we are not on that medical aid. I am so disappointed to think that I am paying for life, vitality, bank with them. I hope someone will reach out to sort out this matter, otherwise I will just move to other companies who will care about my health than leave me without medical cover after claiming they will cover me and my family. A clear requirement from my previous medical aid
