After 1 week, and after being requested to send proof of ID by email, I was told I must go to the bank in Poland.
The only alternative is to ask by phone to transfer money to another polish bank account.

These guys are fraudsters ... Clearly the whole cheap prepaid VISA card scheme was designed for this from the beginning.

I wonder why they asked for my scanned ID only to have it refused after that.

Can anyone tell if they already manage to get an account unlock by going to poland?
I don't want to take a 1000km drive only to be turned back without my money.
