MiWine scam

Received a call from MiWine consultant Tracy. Telesales for cominations of different types of wine. Received an invoice and could not pay immediately. Paid in December and since then have not received any wine, can't get hold of them by phone or email, and I have no idea how to get my refund. <br> Their details are as follows:<br> CDT Laurus Pty Ltd t/a MiWine<br> 011 845 7045/50<br> Email: [Email Removed]<br> Nedbank Merchant No: 2409316<br> <br> I have an invoice and proof of payment and would very much like to receive a refund.
