I was resetting my PC, when I got it up and running again I had forgotten which email I used for Steam. When I tried to login, Steam Guard wanted me to confirm the email that I didn't have.
I tried looking through the Steam support (of course they don't have a contact email) but anyhow, I clicked the "not receiving Steam Guard code" and it prompted me to insert my username email or phone number, but none of those work. Not sure why my username (Vior) is not working (obviously it's not the username of the account, but I don't know how to get that without being in the account)
This is my Steam page.
I hope someone can help me with my issues. Thank you for reading and help.
