The chances of any fraud resulting in a criminal conviction is 1 in 500, that came from Proffesor Marc Button,.
The police are skint, not only do the fraudster get away with the monies, they statistically have a very very slim chance of getting criminally prosecuted.
So every 10000 frauds reported only 20 end up with a conviction, the polices cant say " you have no chance at all" they create a illusion called " action fraud" this makes the people think " fraud" is taken seriously.
Insolvency agency, companies house " good 5 billion fraud every year by abuse of the system" intelligence service, trading standards in regard to fraud by non CE devices being placed on the market.
In short when you report fraud " it's pass the buck"
I'm sorry to be so blunt, you can try the civil route " I know spend more money to get money back"
My advice don't contact any one, thevfraud that I knew took place is in the region of 1 billion and " nothing was done"
