Client not refunding

I have paid this owner R4000 17 Juky 2024 for a shop to rent. Marry told us shop will be ready 1 September and then we can Open. Upon now the shops is still not ready. I requested a refund 12 November. I was told that I will receive my refund 30 November. Upon now still no refund and they are ignoring me.

I told her no one will pay for a shop and wait more than 6 Months to be able to start trading.

Now I'm struggling to get my refund out of them. R4000.
