****med my R6000 by Milo designs

I bought a headboard set with mirrors and paid it up in January 2020, made 2 payments, I have invoices that prove payment, but I never received my goods, when I enquire I keep getting send from pillar to post, I'm told i must send emails to manager who never responds, when I called my calls are no longer answered, I'm even blocked on their Facebook page and messenger page because I kept asking when my things will be delivered, upto now I heard nothing from them, they refuse to refund me my R6000, how can I get these ******** to pay me back my money because obviously they are never going to deliver my goods.
