i think this is the problem with every exchange they such a big usersgroup but nobody to support this. i have raised tickets with 3 different exchanges non of them answer within the week.
one week is normal but i wait 10 weeks and after 4 weeks no more reply this isnt normal and due to the circumstance of the raising usergroup unacceptable. They earn every day millions.
I think you should see thread in accusition scam. there are some problems with bittrex.
https://bitcointalk.org/index.php?topic=1954598.0 many of them get the problem and have not resolved even the support does not give any answer on their problem. I think we should start to be careful on this exchange. I know it feels like losing big money. and support does not provide any help and answer..
