TV? I do understand that your funds are blocked, and I do stand on your side (I'm just trying to separate people who really need help from fraudsters), but do you really think that from the legal and moral point of view you'd convince TV to be on your side? In TV it would go like this "Angry group of blocked anonymous prepaid card owners who used the cards against the Terms and Conditions sues mBank for freezing the cards on the basis of suspicion over the use of the cards".
It depends on the tv/media you choose.
It could simply go like this: "mBank from Poland is freezing clients assets!!!"
If this was a big enough media group I guess they would move. Of course they would say they're fighting money laundering bla bla bla
