Sorry for replying a bit late, I'm new here and not getting notifications for replies is something I'm not used to. We have a similar problem with Payoneer, so many restrictions that it's very difficult to deposit to our banks so people go to Uruguay and use their ATMs to get cash or alternatively they use the Payoneer card to buy things. Unfortunately I have zero experience with Dukascopy, if you have a Reddit account you can try asking in /r/Argentina or /r/merval, some people there have accounts with that bank.
