Membership cancelled due to deformity.

I just received a call regarding regarding a pre authorisation that I submitted on the 02-12-2021 . Discovery will be cancelling my medical aid because of the deformity I have on my toes ( which I recently found out that my corns are actually caused by the deformity) . I thought I just had corns, then I consulted with a Dr who wrote a referral letter for me . That was before I joined them . Then a month later in April I joined . My mistake was actually sitting with the referral letter and not seeing the specialist sooner as I didn’t want to go to the hospital being of the covid cases . Now I’m told that I was suppose to mention that I was suppose to state in April when I joined that I have a problem, how when I only found out in December? Well they are cancelling my subscription, and said they will refund me . Hopefully they will do so as promised. Well I can’t really say I’m disappointed , I’ve had issues ever since I joined . From the membership card taking months to be sent to me.
