yes and for the account owner they must

- provide it for free and process it in due time

- not hide it trying to trick the user into "buying" something to delete their account

through if you have bought one but can not use it because someone else has an account with the hardware you bought from them then the person from which you bought it must do the deletion request for it to be covered by GDPR

and they probably could come up with some nonsense where the account is deleted by the device "stays locked" and you have to pay 20€ to unlock it for a new account

that might still be in violation of consumer protection law, but no longer has anything to do with GDPR and even in consumer protection law will be in a gray zone where you can do little but complain to official agencies
