It totally looks like they are Exit Scammed or they are preparing for it in last 4 months. As my ticket haven't answered in more then 3+ months and it's a easy ticket. As i had the same problem with Bittrex and other exchanges but they solved my ticket in 1 day. Poloniex totally looks very bad right now. As before it was my favorite exchange, but after making the ticket and seeing that they don't answer and don't even care - only then i understood why people was saying that Polo is bad...
But i still have hope that one day they fix my ticket and i can finally withdraw my coins from it
