I need to access my main Google account. I owned a pixel * XL for which I had a RMA setup and authorized relating to battery*charging issues. Before I had a chance to send it it was stolen from my car in Lachute*Qu*bec on my way to Montreal. Can't remember my latest password and Everytime I try to recover it says Google can't verify I'm the owner and doesn't leave me with an option to get contacted or to explain. Of course when I enter my phone number and even my emergency contact email (my sister's work email) Google sends me a code which I enter but the system is expecting it to be on a pixel * XL and not my new phone a LG G* thin Q. I have already blacklisted my pixel by calling my carrier (Fido) but I need to recover my account to see if it's still possible to erase my stolen device but also get all my photos back and contacts etc... I need my account reset and two factor authentication removed since the app is setup on the phone. My backup codes were saved on my G drive (dumb idea, I know). My main account is *****@***.com the email below is to reach me newly created account logged into my new cell phone G*.
