Apple support deleted Granny's Apple ID, leaving iPad and iPhone inaccessible

Granny contacted apple for assistance saying she was unable to login to her apple account so the support team deleted the id completely. Since doing that both devices are impossible to use and you cant erase the content without signing out which is also impossible because find my phone is turned on and can only be turned off by using the password to apple account that doesnt work cause its deleted. Excuse the novel but yeah apple has essentially sent us in a never ending loop with the only solution being buying new products which aint happening.
