LightInTheBox stole over R1000 from me as they won't refund an order they were unable to deliver!

I have received terrible service from LightInTheBox. On 28 November 2020 I placed an order for 2 dresses and paid for the 2-16 day expedited shipping. It was not cheap - everything came to over R1000. I was not informed of the arrival of the package in South Africa - it never arrived at the address provided to the company AT ALL, but suddenly received a message saying that the package was back in China. I have been asking for a refund on the order and I am being ignored. Each time the company says they will give me answers in a few days and then I hear nothing from them. The business has essentially ****** over R1000 from me and now even their "supervisor" simply sends the same copied and pasted message every time, telling me my package is delayed, when clearly it is missing. I would love to take legal action against this company.
