Heart/Cholesterol medication Order cancellation failure with no remedy

With my latest Medxpress chronic order I received an SMS collection notice *** for Clicks Welgemoed. After getting a runaround for more than half an hour they finally admitted that the Tareg 10mg was not available so the order for which I already co-paid R141.57 was summarily cancelled, without informing me. I am furious at this shockingly bad non-service, and non-communication and waste of my time and petrol. However, both M-Khem and Dischem do have stock of this item, so they suggested I simply go and buy the Sched 5 heart drug there, as if it were an OTC non-chronic & non-script drug that I haven't already paid for. My Medxpress on Discovery shows the order status now to be cancelled (unfulfilled), and refuses to let me resubmit it as 2/6 repeat saying not enough time has passed since my previous order of 17/04 even though 31 days has passed. I demanded that this cancelled scenario be repaired and refunded the R141.57 co-payment and my reorder status reinstated for 2/6 so that I can try Dischem. Why was there no follow up and remedy offered from Medxpress. NOTE: THIS IS A CHRONIC HEART/CHOLESTEROL MEDICATION for which my previous script has just run out so status is VERY URGENT. No remedy has been offered to date, and it seems I have been left hanging, I expect a phone call from a Medxpress pharmacist to discuss a solution.
