Bad customer service - Exposing health risk

I have been ordering my repeat scripts with DisChem Mall of Africa with no issues until the beginning of the year this year. I will always order my email through their email as most of the times I am out of the country for delivery. They will send an email to notify that the medication will be dispatch the following day to make sure that there is a person to collect medication and make sure that the money if any is available. On the 11of January I send through an email to ask that my medication to be prepared for delivery without a response, i did the follow up on the following days 15, 19, 20 without a response until on the 21 they told me that my script has expired which on the same day I forwarded a new script. Vuyi responded the same day advising me that there is a levy of R39 and the delivery will be sent on the day. They did send the driver but there was no one at home, so the medication was to be accepted by security who did not and are not allowed to give out money and the driver returned with medication. On the 22 I asked them to send me the invoice and bank details to pay the levies. The same day they send me the bank details with invoice advising me that they will only deliver medication once the payment is showing on their side. Payment was done immediately and POP was sent through. A follow up email was sent through to do delivery of the medication. On the 27 they tell me the POP has been cleared but they can't deliver anymore.

I then wrote back about my frustration in how communication is done and the fact that my health has been compromised in the process. They did not answer any of my email instead they told me they called (through WhatsApp) mind you I told them I am out of the country.

Today I send through another email on dissatisfaction about the service that I'm getting coupled with risking my health. They decided not to respond
