Gadget Galaxy ****med me

I saw an ad on Gumtree. I dialled the number and he gave me a website. On the site I ordered the Playstation 4. I payed him the money and he told me he will send me the product. Last night I still haven't received anything and I called him. He said he'll call me back in 30-40 minutes. When I called him he didn't answer. Today his phone was off. At about 11:40 am today he picked up the phone. When I mentioned the Playstation 4 he ended the call and switched off his phone. I lost R4200.
