I remember some time back a guy here made a similar transaction. He was told to contact the pool than included the transaction in their mined block. Don't remember how this ended though, maybe someone that does could link the topic.
Here is the topic:
https://bitcointalk.org/index.php?topic=602152.0He got refund.
And today somehow I managed to send a no fee transaction by mistake, and it already got 4 confirmations.
Hope I get the other 2 in less than a month
