Misleading information surrounding COVID support - no follow up on customer service

I was required to go for a COVID test. It was quite a stressful time. My plan, after my savings is depleted, has always paid for my GP visits and according to all adverti*****ts, pays for the COVID test. No where does it indicate that it is a "requirement" to do an online assessment before going to be tested. It is also not advertised on the website. I did not think to phone them before going for the test because as per history, my GP visits are paid. Discovery now refuses to pay my GP visit or the COVID test unless I am positive. Spoke to Muagi and then a manager phoned me. Think his name is Tuan or something. He was going to chat with the covid deparment and phone me back within half an hour. I have never heard from them again. I am so disappointed.
