Winnie_ pool,
It does not look good for you to get your money back.
Moneypolo can only return your money if the money transfer did not take place, i.e the money was in their bank at the time BTC-E got seized by the FBI. If they transferred the money to BTC-E/WEX then it is down to WEX.nz to give you equivalent funds in BTC tokens, as they said they will not be able to return fiat funds. There is no way they can return your money if they have already transferred it to another organisation.
As it is now starting to look clear from the other threads on this forum, the team running BTC-E and WEX are basically the same and essentially they are thieves and scammers who have no intention to return either the fiat funds or coins that people had in their possesion. Unfortunately it looks like your money has basically been stolen by the people involved by BTC-E/WEX.
WARNING PEOPLE - DO NOT USE WEX.NZ
btce / wex promises to compensate the user via token, of course there must be fiat. If they do not return, they are scammer.
Who will deposit wire transfer again with new site ? if an incident occurs money is not back to you
