To be fair you got what most people get in the event of a no show, a 50% refund which should by rights show on your stats. I appreciate that your instructions were not followed in that it was finalized when you were unable to log on to make another counter proposal however all finalization's are final, your stats will repair over time when you make more successful transactions. The only thing you could do it try petitioning the resolution admin staff reiterating what happened and see what they say, beyond that there is nothing further you can do I'm afraid.
