I attempted with multiple emails to get ahold of ENVION. they had responded in the past, now no responses in last 4 months to multiple emails. corrupt, but a good early lesson for ICO's. unfortunately many will have trust issues now with an ICO
Who exactly were you contacting? "Envion" is more or less divided as their CEO and founders clashed and sued each others. I think both parties are responding trough their lawyers now.
back when I was getting responses I had an open support ticket and dialogue with someone named Sonja. not responses in last few months though
