R23000 paid for furniture never delivered

I purchased solid oak furniture from Rion Furnishers Midrand to the value of R46 000. I dealt with Ann-Mare Ras. I was required to pay a deposit of R23 000 and was told that I would receive my furniture within 4-6 weeks. That was 10 weeks ago. She does not answer my calls, she does not return my messages and she does not reply to my e-mails. When I do get hold of her she promises that my furniture will be delivered next week......but next week never comes! She has also promised to refund my money, but is never available to do so!
