I contacted Han Group through a website called www.hisupplier.com (http://hanshi88.en.hisupplier.com/?ticket=c45d3580-3494-405c-9c43-35dc600caf46). They are part of / or affiliated to another company having the same address and Managers names called Global Leader Electronic Co. Ltd.
After chatting with the company representative online and then exchanging numerous emails we agreed that they supply me three tablet PCs + accessories for a total sum of 1200 US$.
They sent me a Proforma Invoice and insisted that I transfer the money first through Western Union in the name of their legal representative.
I made the transfer and received no goods.
When I tried to call the mobile phone number they have published on their page a voice message informed me that that number is not in service!
I sent them an email and after sometime they said that they made a mistake and that to get the goods I would have to pay an additional 1000 US$ !!!

I don't know what to do.
