Chronic medication

On 20/04/2018 I visited Dischem at Menlyn Mall (I always go here) to collect my monthly chronic asthma medication which Discovery always covers. The pharmacist informed me that Discovery is no longer pating for it. So naturally I lost it with Discovery only to find out that it was actually the pharmacist that was incorrectly capturing the wrong code to Discovery!!!!! What the hell Dischem!!!! This is chronic medication and not something i can sinply go without!!!!!!! I want this fixed immediately!!! I cannot waste my time driving there if I again will not get my medication!!!!! SORT THIS OUT!!!! I depend on this asthma medication to breathe!!!! Can you not comprehend that!!!!!
