well they can't do anything to refund your sent steem, as the Openledger bittrex account is a squatted account.
i agree,
they could reply more in detail why this is not possible, but in general the support of bittrex is awesome ..
to be honest …
… it feels a bit like u want to blame others for the mistake u made .. don't get me wrong ... i feel you as well but instead of complaining about bittrex let's try to find out who is owning the "bittrex" account on OL and maybe u will have a chance then in exchange of paying a fee to the bittrex account holder on steem..
let's try to get 300 $ worth of votes then u would be able to get funds back in another way .. but tbh .. again your harsh tone is something people won't want to vote for you .. so let's calm down and find a solution not create more problems with this kinda attitude ... i know u are pissed about this situation .. i can feel u .. but u should put your fingers on your own nose ... anyway ..
Just an idea
why not stop complaining and making a good post here with a big warning and HOW TO transfer your SBD in a safely manner to bittrex? I'd bet u could get ur lot approx. $300 bucks back due upvotes ... also informing people about the squatted bittrex OL account .. in this way u would a big chance to get your funds back (with an alternative method) my 2 steems
