Most of invested was me. So i guess they run away with it or lost it. I will go to police and see if they can find them. But its little hope to get anything back.
I think that you should pursue legal action because I think that even though it looks futile, you will be able to be at peace that authorities will have your statement recorded so when they finally catch it, they will be able to incriminate them but the problem is that you should have some evidence to help with your case.
