in my experience the only thing you can do with poloniex is just wait , I had a terrible experience with them in the past and all I could do was waiting till they finally sent me my money ( I waited over 2 months )
I know it sucks but I doubt that you can do anything with it , just please keep us updated

I hope the community will start taking action and stop using these exchanges , at the end they are worthless without users
hope that one of the trusted community guys create an exchange
