You would have to be patient with Poloniex, theyre having issues with their exchange right now with all the lagging and the double transaction withdrawals happening.
My advice would be to keep emailing them. Irritating them worked for me before, but I had the right to since I had over BTC10 in my account, and it was a verified account.
If they delayed your request even though you are verified and with over 25k USD in account then what could we except when we are not verified and with much lower balance? I think that poloniex should increase the number of members in their team because they are getting lots of users.
