No support after testing positive for COVID

I tested positive for COVID last week. Since then I have had to get medication, blood tests, x-rays etc. Discovery did not pay for anything and I could not get hold of anyone there who can help. I ordered my medicine online but they said it would take 5 days to deliver. When I tried to cancel the order, it was not possible so I had to pay twice. They mentioned that I would qualify for an Oximeter but when I tried to order it on the the app, it didn't work. It is impossible to get hold of anyone through the call center. They take forever to answer and when finally answer, they pass you on to someone else.
