Hey @5lvko7stmvt4
As far I'm aware, it's not possible to unlink a platform account from an EA account without access to the EA account.
You'll need to try and get access to your account back, so it might be worth a shot to contact EA Support again.
It's possible that they are asking for the last login location you used that account on, it's possible that they might be using your location to determine whether or not you are the rightful owner.
IP's tend to by dynamic nowadays, so it's not really possible for you to tell them what your IP was at the time, but it's possible that they might've meant the location you usually logged in from.
