Discovery taking advantage of Corona situation - No response to clients

Discovery does not seem to have a live chat option on their banking and their consultants just keep putting the phone down, there is no email contact, they do not reply on their Facebook page.

I am a single mum, I lost almost 200k in expected income since COVID19 was announced meaning I don't know how i will keep going through the next two weeks, never mind the next 3 months. I have no additional income coming in at present. I took some of my last cash, put it on my disc card to pay for essential things for my business = website, etc which keep things going after this!

Now the card has disappeared off my banking and my money is gone with it! No warning or communication from Discovery. No response from them. Where is my card and my money?
