Discovery cancelled 90 year olds policy

I am shocked and very disappointed that Discovery cancelled my 90 year old Mother In Law’s membership after a misunderstanding which we have tried to explain. Unfortunately she did not mention to the broker that she has Glaucoma at the time of signing up on the 19/5/22. She saw an eye specialist on the 16/5/22 for a general check up of the eye pressure, for which we never claimed. She then saw the same specialist in October and without us knowing, they submitted the chronic application to Discovery. We paid the consultation cash. We received a call from an agent and yes, I did start to lose my cool as I kept saying that we didn’t ask the eye specialist to submit the doc and it seems like the agent I spoke to took it personally as right after the phone call I got a mail that the medical aid was cancelled. Being a 90 year old woman, my Mother In Law was asked to sign a form which she clearly didn’t understand what she was signing. We have been trying through our broker and emails to resolve this but to no avail. We haven’t even received a response to the direct emails sent. We then received an email last week basically confirming the cancellation. Totally unacceptable service received from South Africa’s best Medical Aid!!!!
