Pathetic handling of a simple issue by Discovery Health

On 28 July 2021, I sent the documentation to change my medical aid from a company contribution to a private contribution. I enquired later and was told that Discovery never received my email. Then on 27 August 2021, the email "magically" got actioned and Discovery admitted that they DID receive it on the 28 July 2021. In the meantime I was basically treated like and idiot because I kept on referring to a non-existent document. After a lot of emails, I have now paid the August subscription in cash as my account was supposedly terminated at the end of August. This is totally inefficient handling of my problem. I need my cronic medicine as I have now run out but Discovery is not interested!
