I have a customer who has locked himself out of his gsuite account. He created an admin and then deleted his personal account. He does not remember the admin account or password he created. Literally, we cannot access the gsuite account.
Google's support is notroriously horrible, so I'm actually posting here. We do have access to the DNS for the domain and we can add CNAME/TXT record etc to prove ownership.
Does anyone have any experience with recovery using this method?
