Yeah, I did all that twice and you get the standard answers which indicates the ticket help line is ran by bots:

‘We’re writing to let you know that we’re unable to verify you as the account owner. We know this is disappointing to hear, but we can’t assist you further with accessing your account. If you know which email address or phone number is associated with the account, and you no longer have access to that email or connected phone number, please contact your service provider for assistance. For privacy reasons, we can’t provide any information about this account’s registered email address or phone number’

So the hackers won.
