Truly Good Food - poor/no service

On August 15th 2020 I ordered a few items from Truly Good Food online. I checked out and made the payment of R531.00 via PayFast. When I did not receive my order, I had a look at their website and realized that they do no deliveries to our town (Kleinmond). On the 10th of November I sent them an email about the matter and asked them for a refund or a voucher to the amount I paid. The voucher I could redeem at an outlet nearest to me. In my email I included 2 documents of proof of my payment. Surely my payment would reflect on their bank statements. I had no reply from them. On the 3rd of March I sent them an email again, asking them to look into the matter. Still no reply. Can it be so difficult to just reply to my enquiries? Very much disappointed.
