Unauthorized debits and it's not stopping

I regret not listening to my friends when they told me that Bonitas should be the last option if I was to apply for a medical aid. I went ahead and app**** anyway and I must say I made the biggest mistake of my life. I believe I app**** around January/February this year and upon receiving my membership certificate and seeing the limitations I decided to cancel. This was in February. I still have not received a membership card by the way. The consultant told me that since this was a new application, a cancelation request would be escalated immediately. There I was thinking I'm done with Bonitas only to find out at the end of the month that a debit order went through. I've now had to request stop payments with my banker because of this ****. I want to make others aware that this medical scheme is just a money making scheme. No customer service whatsoever.
