Don't hope yourself with empty promises from MT.
how they could send cards if they do not show any terms and fees for new card provider?

actually, they do not have new card provider and don't get in soon.
Usually it's a long process and you can see on other EMI who were lost cards because of work with crypto - almost nobody recover card.
And few ones who do it (wirex, spectrocoin, etc) spend almost year for it.

Just go to another EMI who could give you a card, instead of listen infinite promises from support that is actually useless.
