Avis Took my money and delivered no product

I had ordered an Iroko log from ETS Nomade Trade and Mr. Johnson Atu. I was sent an invoice with proper shipping terms and I wired my money to them. I received a few communications from them and some excuses of why I was not getting any updates on my shipment. Then I didn't hear from them for a while and he contacted me with a story of needing more money before he could ship my product. I informed him that we had already negotiated the deal and he was already paid. He has so far refused to send me product and has stopped communications. He was wired the money at the end of September 2017. To date I have received nothing.
