There are a lot of “Poloniex” is slow posts, and think all of them resolved without problem,
As far as i can see, they take their sweet time, and a lot of people don’t send a message with the deposit, making it complicated to discern which transaction is which, thus long waiting times.
There was this post but it doesn’t specify what to send in a message…
As for your funds, they are with poloniex and you should make a ticket with them, as it’s not in NEM anymore, and NEM can’t help you retrieve funds.
i sent 1,000 xem to changelly, they said it is not in their account and i cannot find it in my history either but was debited, they are asking for hash but no such information in my mobile app to send. please how do i recover my xem?
