Unable to access medication - oncology patient!

I am an oncology patient and cannot access my cancer medication due to some system mismatch of Discovery. It takes 3-5 working days for them to investigate this matter. The issue is that I have no more cancer medication as I have run out of my medication and I cannot get any because they have drained my MSA by paying for cancer treatment from my MSA, therefore I cannot get access to my medication. This is unacceptable as I have an approved Oncology benefit and have the necessary authorisations for my treatments, I have done everything that is required to ensure that i get the necessary health and treatments and now Discovery is doing me a great injustice. I need my cancer medication two days ago already! We are not talking about flu medication here, we are talking about cancer medication! Discovery you have now put in a very vulnerable space due to this as this is day 2 without my medication. Please have this issue resolved immediately!
