Got an update from the bozos.
They have been swamped with negative reviews and complaints, and are partially giving in. They claim to have reactivated account logins (verified - I can now login again) and the cards (not verified yet). They say transfers are "limited", they don't say how, they probably mean effectively disabled. We still have two months to clear out of there.
Email:
Further to our previous notice please be informed that your account is accessible and your card is operational for the period of 2 months notification.
Outgoing and incoming transfers are limited due to termination of your account.
Our previous notice︀ in this regard remains in force.
