Extremely disappointed

I am very unhappy with the fact that Bonitas changed the pharmacy to Pharmacy Direct to get your chronic medication from. I used to get my medication from Dischem with no problems, now it has been a battle. I was responsible by getting my new, updated script for my chronic medication in time, only to find out that Dischem wont cover any of the medication. After contacting medical aid I had to learn that I need to get my medication from Pharmacy Direct. After a struggle of one week I finally got them to confirm that they have my scripts only to be told that it will take 5-10 days for delivery. I am without my medication now. If I could get it from Dischem like before there wouldn't have been any problem. The question is, who will take the responsibility when something happens to me because I am without my medication? I have hypertension and diabetes, both conditions can my life threatening when you don't take your medication. Will it be okay if we sue Bonitas medical aid when something serious happens with me and my loved ones are left with questions and it can be prevented. I am extremely disappointed in this matter.
