Non Delivery of Medication / *****ulent claim

I ordered meds online through Discovery Medexpress on 31 January as I have done for many years and received a confirmation that the order had been captured and to expect delivery as usual in 3 to 5 working days. I waited for the 5 days and on not receiving any delivery or notification called Discovery on 5 February. After a 30 minute call it was confirmed that Clicks Direct had cancelled the order without notifying me or Discovery, the reason given that 1 item was out of stock. Urgent request for Medexpress to contact me and sort out. No response. I called again on 7 February, escalated to supervisor and another urgent request for Medexpress, today 9 February still no response. The cost of the order, R1232.47 for 6 items, which includes the 'out of stock' item was logged on Discovery as paid to service provider and cleared on 05 February and deducted from my savings. I have not received my meds which include chronic medication, Clicks Direct Pharmacy has claimed and been paid, I consider this a *****ulent transaction on both sides. The same thing occurred in January when Clicks Direct failed to process an order and did not communicate the reason. Again I had to contact Discovery only for the consultant to be told that they would not share the reason with her and again had to wait for Medexpress to assist which they did. Discovery Medexpress has failed me and so has their service provider, Clicks Direct. How many more times must I contact Discovery and Medexpress to sort out Clicks Direct? Bottom line is I still don't have my medication which includes 2 chronic items.
