Hi.
I am sorry to hear that they did that to you .. this is crazy.
I am not sure how to help. I cannot unblock any more cards on my ID and to find someone who will trust and will provide his ID might be hard.
I did it only because I have full trust to Pagie but I wouldn't do that for anyone else.
Anyway I cannot unblock more cards but I will try to ask my friends and maybe someone will be interested but I highly doubt because of full ID registration to the card which might be risky and dangerous.
If I will find any solution I will let you know.
I am also pretty sure that mBank will find a solution on their own soon.
Mbank is a very good bank in Poland I have mBank's account from 12 years ... they are not scam just those prepaid cards went wrong.
Regards.
