I'm in the same situatuion.
Made a EUR SEPA deposit on 24th of July.This deposit was never credited to my WEX account after the seizure of BTC-e.
WEX tells me to contact MoneyPolo, while MoneyPolo claims they can't help me and they already refunded all the money of BTC-e clients.
After I asked WEX to contact MonpeyPolo to solve this issue, they replied the following:
Hello!
Sorry we are somewhat busy, in order to contact MoneyPolo
Best Regards,
WEX Support

They obviously don't want to help clients to solve this issue.
