Disgusting staff at head office and non functional email addresses

I have sent many emails and calls to these *********** people. The last person I spoke to reassured me that he will keep a line open to receive my problems. Up to today he hasn't done anything. He hasn't responded to my emails. They don't want to pay for my doctors expenses which were paid upfront. I pay over R14 000 a month and they can't even sort out a simple problem, not mine but theirs. Hello, Is anyone listening out there. The most irritating thing is that they don't care because they have a 3rd part email who don't even send the emails to them. We as clients just suffer because we can do nothing about it. I think this is also ***** and *******ion. They are silently abusing us and then refusing to assist us. I am really very stressed and upset by GEMS attitude
