The problem is here that we send money to this fraudulent person via Western Union... and this quite difficult to track and get back...

Ah... if it's going through Western Union, there's pretty much nothing you can do about it other than report this to the proper authorities (the FTC, IC3 and Ecommerce.gov: http://www.sitejabber.com/consumer-information/how-to-report-online-fraud-and-scams)

I'm sure you know this now but ANY websites that asked to be paid by Western Union are scams.

This company is FAKE. The £1900 collected at WU should have been collected in Ireland. It was collected in London. The FS are looking into this. CASH sales are NOT made for 20 - 30k machines with no documentation to back it up. I am glad Mr Diaz is aware of my comments on this web site (just see last 4 comments posted - JOKE - sound like they were written by the sole "customer service" rep of the 24hr shipping co) You can now look forward to meeting the FBI as they have all your details. To verify your business I'm sure you cannot wait to post your company registration details to this web site to prove to all that you are legitimate.
I like the smiley photos - funny how the good reviews were all sent on the same day.

This is excdllent info, although you would wann be fairly thick to fall for it, without checking him out.
