I made a payment of R150 on 10 June 2021 and sent proof of payment on the with an urgent request to send my insulin ad I'm out of meds and am diabetic

I'm type 1 diabetic. I've paid a copayment on my insulin on the 10 June 2021 and requested they send my insulin and blood thinners urgently as I'm running out. Since then I've been sending emails and calling the call centre and still don't have my insulin. I have been without my meds for a whole week. Yesterday 17 June I was told that my meds will be sent and I will receive an sms as confirmation.. nothing happened. I called at 9.30 this morning and spoke to dipuo who read notes from the system that the manager said my meds must be sent today and I will get an sms. It's now 12 pm and no sms. I decided to call again and spoke to Bridget who told me the meds will not be sent out coz no insulin is sent on Fridays. I asked to speak to the manager she said the manager is not available. She will ask them to call me back. I asked for a supervisor she said no coz only management can make the call of sending the meds today. So my question is, who must I blame if I die today? Who will take responsibility coz no one wants to take responsibility to send my insulin. So I'm expected to wait till next Tuesday... meaning I must still go a full 4 days with no insulin. I'm extremely upset and disappointed. No one is taking this matter seriously. They use the term urgent so loosely coz none of them did anything to make sure my meds are delivered. Everyone just reads off the computer and that's it.
