Discovery misleading app information

I am extremely annoyed with Discovery. I went to the Doc on Monday and only had to pay R50 co-payment because I am on a Smart Classic plan right? After the Doc gave me the prescribed medicines, I looked on the Discovery app for the closest Full Network Cover pharmacy which was Dischem Atholl Oaklands so I go there and get my medicine, the pharmacist says to me that this pharmacy is not covered therefore I will be liable to pay full price for the medicine instead of paying a co-payment of R10 per item. So I innocently think that there must be a misunderstanding because I found this pharmacy on the app so I say to myself, it's okay, I'll just put in a claim and they will reimburse me. I submit the claim and phone yesterday to follow up, only to be told that because I had selected Clicks as my 'prefered' pharmacy on my profile, anything at Dischem I would need to pay full price for. That is outrageous! Just because I prefer using Dischem should not limit me and not allow me to use Clicks as well, surely?? And if my profile had Clicks selected, then why is the app even showing me that Dischem is a Full Network Covered pharmacy (when at that point, it's not covered at all)? That is so misleading! Please could you update your app to ensure that only the pharmacy that is selected shows?? I had to pay R750 out of my own pocket that was not budgeted for, just to help me get better because my medical aid mislead me into believing that I could use either Dischem or Clicks, which are both partners of Discovery anyway?! Highly disappointed regarding this and this has never been clearly communicated or explained. I do feel that the app should change and only show relevant information.
