Pharmacy Direct bad service

Pharmacy Direct has my chronic medication script. On 7 September they claimed from Bonitas and I paid the difference. On the 14th I contacted via whatsapp them to find out when my medication will be delivered. I told them I have medication untill Sunday the 19th. I was told my medication will be marked as urgent. I phoned them again this morning and was told the pharmacy is processing it and it will be delivered on the 20th. So what should I do about the early morning medication I need to take before breakfast on Monday? I'm still waiting on the manager to phone me. This is ridiculous. They claimed on the 7th already, but I'm still waiting.
