999k maybe worth it.
100k walk away...
As someone said above plan some kind of revenge but make sure u never see this man again, if u do that and he loses face Ur in a bigger mess then u are now.
I don't want or need the answer.. I just can't stand people who say they know the solution and it's easy but don't bother sharing it to help people out cos they don't know really , it's just a form of bragging without know anything.
