Impossible!!!!!

I want to rate a zero!! So quick to sell you the medical aid scheme but impossible to get a hold of! I have sent countless emails since two weeks ago, I have called the contact center 100s of times! I have cancelled the policy and I was insured they would not charge me as I cancelled well in advance ( before the start date of the policy) I'm now being charged for a service I did not use! I have called again today been on hold and then told the call center is closed!
