Why does the EA customer service agent need my Ip address and DOB

Hi Darko, I am hoping to try and understand this a bit more because we are having issues accessing an EA ID account and have tried going through this process several times. I am unsure how the IP address helps genuinely because the staff member didn't explain what IP address they wanted, just that they wanted one. So how would my PC IP address be of any benefit to them?  How does having it help to access an account?  What if I had created the account on a laptop I no longer have?  I am honestly confused about the request for the IP address.  I am fine with the DOB and phone number etc

Hey @CBozza13 if you have any questions related to gaining access or proving ownership of an account then you will need to direct them to our live support team.

Typical EA response.

Hey there!  

This thread's getting old, so we're closing it to avoid any necroposting. If you have more questions or want to keep the chat going, please start a new thread! That way, things stay neat and tidy, and everyone can join in. 

Thanks for your understanding. 

Hi, your live support team was not able to help me.

I had an old email that I deleted because I swapped everything to my other social media email. Was hoping to unlink the old EA account with that old email from my steam and link the new (since I want to play the new Split Fiction game and A Way Out game), but I had no luck. Tried talking to live support twice and they both said the details for my own account was wrong and no one could transfer me to a supervisor. They said "Only you can help yourself". 
I also already tried Steam Support, and they advised only EA is able to unlink the Account. 
Please let me know if there's ANYONE else that can help.
