I will give you the deposit wallet private key, how about that, what more can I do to prove I sent this, I quickly posted here and sent a support email the same hour after the deposit was made. I still have the tab open and can prove anything you want. Jesus
If they didn't reply to any of your emails (I don't think this is a good behavior like I said), than I don't see what's the point in sending them your private keys

I hope you learned an important lesson from your own mistake, and next time be extra careful when you use any mixing service.
There are some grey areas with whirlwind, but most is related with user mistakes that can be intentional sometimes.
And btw most of the neutral people from bitcointalk voted to for WhirlWind not to refund funds in cases like this.
Out of over 5 emails to customer support I got replies for ZERO, in 2 days it will be 1 week since the first message
Put yourself in their position, if they start to reply and refund everyone who makes mistakes, they could compromise their security model and potentially get attacked by someone.
They left me in the dark, I wasnt even human enough to deserve a reply.
