Account support query

Hi all.

I wanted to log into another one of my phones with my account and every time i tried it kept giving me the error that either my pwd was incorrect or theres no account associated with my email.

Reached out to support and they keep asking me these questions in the image

I cant for the life of me remember most of these details. Went back and forth with them and i keep getting the same response and try my best to remember this info.

Saw somewhere in this subreddit that people were able to find their account age using socialagechecker.

I was able to figure out my account age with a social age checker website and reply with all the details according to that time period.

I still cant seem to get through them with this information? Getting the same response every time and it feels im talking to a wall.

How do i go about this?

I dont want to lose access and now im afraid of logging out from my current phone, incase i cant get back in.

What am i meant to do in this situation?
