You shouldn't mine directly to an exchange to begin with.
I am sure Poloniex will get to your ticket in time, something that won't help is putting in more tickets or spamming the ticket angrily.
How can you make sure poloniex will get to his ticket in time? Since when do poloniex get to our tickets in time? I've never seen this. They don't care about tickets.
I had several problems 2 months ago, still got no response.
And note that, never mine directly to exchange wallets, as one of the users said above. Collect into your wallet first then transfer it to the exchange.
