Unwilling to fix issue caused by their Android App.

Recently installed App on my phone for vitality as I have recently started going to Gym. In the process of setting up my profile on the App, the app crashed.

2 weeks later, I go to the Dr for an illness, get prescribed medication and go to Clicks. Pharmacist tells me that the system says they are not the preferred partner and Discovery will not pay.

I call the call centre. I have apparently chosen Dischem as my partner on the app! I have not done this, as there is no Dischem near me. They cant / are not willing to resolve this, saying that I need to wait until January.

I am currently sick as a dog, and cannot get my medication prescribed to me today.

Next issue I have is that my chronic script is loaded at Clicks and that In the next week or so, I will need to get this dispensed but will be unable to because of Discovery? Am i expected to go a month without my chronic medication?
