Discovery *****s your money... Watch out

I've had it with Discovery. I cancelled my Discovery medical aid last year medical aid with them at the end of September 2021. They've been debiting my account ever since and are refusing to repay MY money as they say there was an outstanding payment for October 2021, how is there an outstanding payment when I cancelled in September. The gentleman on the phone last year assured myself and the FedHealth consultant (we were all on the same call) that there will be no penalty for cancelling, but never cancelled it. My biggest issue is, why was there no communication from your side stating that there was an outstanding payment in the first place... This has really put me out of budget and I'm definitely lodging a complaint with the council for medical schemes and will post this on every social media platform until I get my money back
