Extremely TERRIBLE service !!!

I ordered foundation from the website on Thursday 11 June 2020 and paid the same time. R99 courier fee was included - on the website it clearly says NATION WIDE. On Sunday 14 June 2020 I received my tracking number, but no information came up when I tried to track my parcel. On Wednesday I phoned the couriers and they told me that the package was still with the supplier. I then emailed Callendra and they then only told me that they were not able to send the package as courier fees were about R400 to me. They wanted to refund me the R99 if I could arrange my own courier. I then suggested PAXI which is a lot cheaper, but from there on I got no replies on my emails and my whatsapps. On Thursday I phoned them after again getting no reply on my email and then only the lady said that they would discuss it with the manager and get back to me. At around 17:00 they let me know that they would be able to Paxi it and that they would send it early Friday morning (19 June). At around 14:00 on Friday I sent a message and asked them to please refund me if the package has not been sent yet. I was then told that they would send it to me in a short while. Later Friday at around 18:00 I asked for my tracking number and got no reply. Saturday I sent messages to all the Callendra agents - NO REPLY. Monday morning (22 June) I phoned them at around 10:00 and I was told that the package would be sent to me within the next 30minutes. It is now Monday 22 June 12:30 and the package still has not been sent. I don't know what to do anymore - they make promises that the package will be sent and nothing happens and I also don't get refunded. I have NEVER seen service so terrible as this ! It might be a wonderful product, but with service like this they definitely won't last very long.
