Pathetic Customer Service From Discovery

What a horrid experience received from Discovery medical aid. I must say I am absolutely gobsmacked. I had a keycar package with them as I am a freelancer and do not earn a lot, I received a letter stating my monthly repayment will increase from R3k per month to over 6k. I notified them that this is unaffordable for me and I would need to cancel. I received my cancellation reference letter and left it at that. This morning I phone them to ask why they were trying to deduct A WHOLE R12K from my account. Would this call centre agent not tell me that it's not his problem and I should get my finances in order!!! How insulting of them, nevermind he refused to give me his name when I asked him. Forget Discovery, if this is how you treat clients I am glad I left...
