We take your account's privacy and security very seriously, and we'll only let you reclaim an account if you can prove you're the rightful owner.
When you register for an account, it's up to you to provide the most up-to-date and valid recovery info. Your best option to avoid losing access is to update your recovery info if you get a new phone number or change your alternate email address.
To get in to your account you need to use the sign-in helper found here which will send a code to the recovery phone or email that only you have access to. If you don't have access to recovery you can't recover.
It is an automated system, if you don't have the needed tools no one can help you.
Make a new account and be sure your keep recovery up to date to avoid problems like this in the future.
