http://patersonandquinnma.com/ has scammed my father

My dad has recently sent almost $30,000 to these people in China and now they won't return his calls or his money. Paterson and Quinn said they needed a bond from my father before they could sell his shares for him and said they were experienced in China for over ten years but my IT co-workers tell me the site is a new one and they are not real. My father is distraught about this, what can I do ?

Is http://patersonandquinnma.com a scam as I think it is and can we somehow get the monies back to the UK ?

Any advice will be helpful, my dad spoke to a Mr Jason Hill at Paterson and Quinn and was told he was guaranteed to be paid in full.
