Hey Roslinpl,
I wanted to check how's your work on the embassy going and stumbled across this thread. I'll PM you for details, there might be a way to help. I talked to my cousin, she used to work at mBank for a long time, she still has friends there, it might be possible to sort things out a bit. It all depends on the number of cards to unblock, we'll either go to a "friendly" branch:) if the number is not that high, or try to force the matter from the inside, with the help of people working there.
Anyone directly involved please PM me so I have a total number of cards that need unblocking.
Kind regards,
Piotr
