Seems like they don't even care to answer
Of course they do not care, they are selective scammers. I believe their tactics is to frustrate people to the point were they forfeit their funds to them and forget about it.
Do not use changenow or other platforms like this if you value your time and sanity
That's very obvious now, as a matter of fact it was obvious even before they seized your funds, because of the number of similar cases all over the internet. If you make any progress through the law firm you said accepted your case, please share or post an update.
