Pharmacy direct worse pharmacy ever

My mom in her late seventies, has stage 3 cancer using OPMED medical aid scheme, I forwarded her prescription to Pharmacy direct a month ago. A week after I called to check whether they had received the prescription. I again called two weeks ago to check and was assured that the pharmacy is busy with her prescription and that the medication would be delivered the following week(Monday). I called again yesterday to check when the medication will be arriving as it has now ran out. only then I was told that they had a problem with her medical aid number. which is strange because when we collected her medication from Clicks Pharmacy claims went through with no hick-ups. The excuse they spoke to her and was waiting since the 23rd September for her to confirm the correct number. My mum sent the confirmation the same day in September. We confirmed the number again yesterday and was assured that a consultant will call and give an update. Nothing happened. I called a few minutes ago and the same story of yesterday. What is worse no one calls you to tell you there is a problem, even though we had changed the cellphone number.
