Got a strange issue here involving Coinbox and about to be locked out of my wallet

i have some money in the coin box app, but they’re saying i have 3 days before my wallet will be disabled. However I can’t take money out as ‘this action has been blocked’. So, are they flat out stealing my money, or something else?

I have my seed phrase, but i can’t import it into another account as it needs to be converted. Fuck.

Any help/ideas will be greatly appreciated.
