Chronic illness Medication Not delivered

I would like to lay a formal complaint against your Discovery Med Express service not delivered. I have run out of my chronic illness medication because they informed me that i could not complete an order for June as the system shows them that my meds have been ordered in advance. I had meds for June but they could not last me till the end of June. <br> The re-order sms did not come through thus Monday 29 June 2015 I called Med express and explained my situation. I spoke to Ronel who said she can arrange with Dischem Parkstation and i can go pick up my meds later Monday or Tuesday morning. Later that day i got an sms saying Dischem was out of stock and i had to call again. I called several times to make other arrangements and a lady by the name of Melanie hung up my call after i was trying to explain my crisis to her. I called back again and spoke to Babo and Amanda. <br> Amanda was very reassuring and arranged with Med Express courier company to have my meds delivered yesterday. She went to the extent of calling me Tuesday and reassuring that arrangements have been made and my meds would be delivered. My meds have not been delivered, i am sitting without medication and lost on what to do.
