Poor service

I recently changed medical aid options and the option I'm on now dictates that I only get my medication through medxpress, which is a service provided by the medical aid. I faxed my prescription to medxpress as required and did not receive any acknowledgement until I had to phone. I could not be assisted due to an error on the script. The script was then rectified by my doctor and resent. I called 3 times to check on the status of my prescription and all 3 times I was told I could not be assisted due to technical problems. I called again the following day and my prescription supposedly processed. I went to the pharmacy the following day to collect my medication, but only got less than a quarter of my script. I then went back the following day and still no medication. It's been more than 7 days of no medication and I am diabetic. I've now run out of insulin as well. Discovery is putting my life st risk, yet I pay my medical aid monthly without fail. I am disgusted by this medxpress system that they have enforced on us, as all it does is compromise our lives.
