Pharmacy Direct Delivery Service

Good day. We are obligated by Bonitas to use Pharmacy Direct. We stay in Northam. Some months they deliver our meds late some time the just drop it at a pharmacy with out informing us then 2/3 days later I find it standing on the floor in a temp of 40 plus I am a diabetic and my insulin is suppose to stay in a fridge? I had to stay without meds previously for a day or two. We do not stay near to town. This been going on for months now. This month we got a sms say on the 9th they will deliver after numerous calls, whatsapps still cant find my meds. People that work there is not the problem it is the delivery service.
