From my experience Poloniex is one of the best exchanges in the cryptospace. I would wait a little while longer and see how things turns out.
In general I trust Poloniex on the same parallel as I do Bitstamp.
I wouldn't mind the wait if they would give a clear answer, when they won't answer questions or give you an answer that you know is a lie then my trust for them dissappears.
