Unauthorised debit orders

I app**** for key care medical aid for my unemployed mother who is a pensioner last year March. Her premium was supposed to be R2500. On the 30th of Jan, I received a letter stating that she has been placed on a higher income bracket and her premium will increase to R6000. I immediately responded and told the guys I do not authorise the debit order and it’s very unprofessional of the team to send a letter a day before the premium is due. Nonetheless, they went ahead and debuted my account. I have never received any communication before this date relating to this.

I see a lot of other people are complaining about the same. How *********, unprofessional of Discovery, they lack integrity. They increased the premiums for the keycare members without any notification and they keep insisting that they sent an email. They lack integrity, and they enrich themselves at the expense of ordinary citizens. I will definitely cancel all my policies with this company, I will not be associated with such!!!
