I have a Facebook account that was created about * years ago. I never used the account once I created it. I have tried to reset my password, however, I have been unsuccessful as I can't remember the details I used to created the account. For the past *-* weeks I've been receiving text messages that my account was logged into from locations around Australia. I've tried to secure the account, but as I can't log in, I can't do that. I've also sent the message via the text link to tell Facebook that it isn't me, but the alerts just keep coming through. The last alert said the following: "Your Facebook account was recently logged in using a confirmation code and email address *****@***.com on Sunday, September **, **** at **.** (UTC***). Operationg system - Windowa, Browser- Chrome, IP address ***.***.***.*** Estimate- Mount Martha, Location - Victoria. Can you please help me to shut down this account and remove any access using these details?
