Disgusting customer service

Absolutely disgusting customer service. My husband has been trying to get a query resolved for over a week now. He has called the contact centre now 4 times, spoke to 4 different agents, had to repeat himself 4 times each time the agent promised to give him feedback and to date not a single call back. When he requested to speak to a team leader with the hope of getting the query resolved he was put on hold for 15 minutes and he was calling from his cell phone. We have all the details, the dates he called and the agents he spoke to, and the complaints functionally on the website doesn't even work. I am appalled. I pay over R100 000 per year to this medical aid yet we are not important. That is what Discovery Health thinks of their members. ABSOLUTELY DISGUSTING SERVICE...THEY TAKE MY MONEY VERY QUICK BUT DELAY WHEN THEY HAVE TO PAY ME BAC****!!!!!!!
