Poloniex support activity is really going down the drain. Are they still processing tickets or not?
They're still processing tivkets, they have a backlog. And the backlog isn't helped by people posting multiple tickets, which just go into teh queue behind the original ticket.
You could try posting about your problem on the following thread:
