Did you sent to steemdollar adress in Polonex? I had almost the same problem. I sent some steem to bitcoins adress in Bittrex. I didn't recieve anything. I think I should have sent it to steemdollar in Bittrex. I tried to ask it back, but no want reply. I lost around 150 US Dollars. Good luck @ Chanthasam
I sent the funds (now don't laugh) both SBD and Steem to the appropriate accounts yesterday... yup out about 1000 so far.
Did you contact to steem? I don't know, how to contact them.
