I also made a mistake with Bittrex, sending Steem to my Bitcoin wallet instead of the Steem one by mistake.
They dealt with my problem in a little over 24 hours and refunded me in a little over 48.
So my experience has been good so far, I'm sorry to hear about your problems, I am new as well so don't really understand Openledger. I hope you get it back.
Cheers

Thanks CG. Yes, I am glad you got your refund.
[Edit] I admit that I was upset that bittrex didn't offer resolution options, but as mentioned below, they handle many requests and there isn't anything that can really be done in this case
