Good day the transaction went through your site but nem crypto calls did not reach the site account poloniex.Because my account is not blocked. Therefore, I ask you to send nem crypto votes to another purse. Here is the address .NAYXWO-TLHZEN-5CCDAM-N3PQXF-RTQ573-GC4IXM-YLIF And here is the proof of the transpositions.
So you sent XEM to Poloniex, and they are saying they never received the XEM? When you send XEM to Poloniex, they ask you to attach a message. Did you send the message along with your XEM.
There is no way to reverse a transaction, that is one of the main benefits blockchain provides. Only Poloniex can help you.
If they are able to refund you your XEM, they will be sending the XEM to the same address that you sent it from, not a new address.
What address did you send the XEM from? I can help you get the transaction hash.
