I've lost my 2FA device and didn't had an backup. I wrote to them 4 days ago and got one response but then they went silence. I've provided that i'm the owner of the account with passport selfie and proof of NXT address which i've used since 2 years non stop for Poloniex. . Anybody a idea what to do else? I've huge orders open and one of the highest trading tier status but they just don't give a fuck.
