False information used to make decisions

I app**** for discovery medial aid on the 04/09/2020 ,I was asked if I was pregnant or have any pre-existing condition I know of ,and I said No,I actually mentioned that I struggled with headache a few years ago but I am fine now. On the 9nth I found out I was pregnant and went to the doctor ,I did the blood test and have the results,now discovery is refusing to cover me for my pregnancy because they classify it as a pre-existing condition,though I was not aware I was pregnant,I mean if I knew I were, I would not even consider taking their medical aid. Also they keep on using false information which says I am 31 weeks pregnant which is false and I did send my confidential medical results to discovery to prove that I am not 31 weeks pregnant which is being ignored. I wanted to cancel the medical aid the first time I found out but the consultant told me to inform discovery because I did not know,but this is a complete waste of my time.
