May be better way to go to MBANK? I am going there in October. Give them my ID and hope to get all my money from 3 Prepaid cards.

Also, dont you think, that we re not only one, who has these cards.
I think, that a lot of people in Poland have the same cards, the same problems and they can go to bank anytime and I am sure, that they did it already.
May be someone has friends there or... who can google Polish forums to find any information about that?
