Caution! Support Poloniex ignores your ticket if there are any errors in transactions.
I have issued a ticket according to their rules. This ticket has been ignored by them for more than a month. Support Poloniex pretends that this ticket does not exist.
I doubt it's them ignoring your support ticket but rather there is just so many problems with their platform that there has been a huge backlog of tickets waiting to be processed and yours is probably of quite low priority.
Poloniex is a buggy exchange at best and a scam at worst, speaking at this point. I've got coins stuck their too.
If you have any balance in poloniex you should consider it gone, whatever you withdraw is really coins that you have earned. Don't expect a timely response from support, and don't send in multiple tickets without some time in between, otherwise it'll lead to their system being more flooded.
