I'm also having the same problem with them my ticket was over 18 days , no reply I try to reached them through their slack channel they told me tickets take several weeks especial the low priority until yesterday they kick my ass out of their Slack.
My money was stuck there no trading , No withdrawal , nothing and nothing empty account.
I wish they would just let me withdraw from their site and move on with my life. They really got me angry and stressed yesterday. I have even uploaded my passport. Why do these exchanges not have support? I guess it's difficult to find people but if you are making that kind of money have a plan. I am going to wait another day and then keep on a posting run warning everyone to avoid these people. I'll try to be more understanding but jesus, they even banned me from the chat room for asking.
Really friend 0.11BTC and a very small amount of somehow so the bittrex might want to steal. What happens and due to the skyrocketing price of btc has brought many new customers and all exchanges are not accounting for the volume the service is horrible.
With a little patience you should be able to get your bitcoins back.
