I have a similiar experience with google. I had an old google account with an old email address that i use for work. I had access to said email mind you. With my work number.
The thing is, i want to delete it. Dont need it anymore. Yes, i can just ignore it and move on with my life but i dont want that email and my phone number tied to that google account anymore. So i did what any sane person do. Login and delete, right?
No. Fuck me in particular. Google wont let me do it. I can login BUT anytime i tried editing anything sensitive like my name, number, deactivate 2FA or in this case delete my account, i hit a wall. Something about they cant send 2fa code to this number at the moment or some shit. Cant verify the owner fo the account. Motherfucker, i have the password, the email and phone number. What more do you fucking want. The thing is, they CAN send me a code when i login. Why cant they send me when i tried to delete my account. Bunch of fuckers.
I gave up and enable inactive google account. 3 months time, supposedly google going to delete the account. Who knows. I swear, bunch of bots is running that company. Cant even find proper help. Fuck them.
Everyone in their right mind already figured this out eons ago ffs. The point is, what the fuck are you going to do about it. Same headline probably gonna come out next year. Rinse and repeat.
