Hey ejxnp4yb944f,
Sorry to hear someone else had gotten into your account. If you haven't already, you'll want to connect with our live support team for assistance recovering the account, as they'll need to discuss private account details, and we can't support that here on the forums. An advisor will need to verify your account ownership first, but should be able to help update those incorrect details afterward.
Once you regain access, please be sure to go through as many of these security steps as possible to help ensure your account is back under your control. It'd also be worth following the recommended security steps for your email address and any platform accounts linked to the EA account.
Let us know how it goes, thanks!
