If you did not sign out that AppleID on the device before you asked Apple to delete it, then it is a brick now, as explained in the documentation you read when requesting the AppleID be deleted. Apple will not be able to do anything for you now that the AppleID has been deleted.
It is very important when asking for an AppleID to be deleted to follow the directions explicitly. Once the AppleID is deleted, there is nothing anyone can do about it if it was still signed in on any device.
