Discovery can you respond to emails and pick up the calls

I sent emails to Discovery from 18 Jan to *** (the agent/broker), *** and ***. No response. I sent a second email no response. I call go through all the hoops of inserting my medical aid number, listen to all the prompts choose the right one i.e. speak/hold for a consultant. Then get cut off. Can anyone get back to me. I need to move my medical aid over to my company and because Discovery is just not responding this cannot happen. I am so frustrated. Why must I go onto a public platform to get some assistance.
