I have yet to have any positive interaction with Steam support. If I had, then I wouldn't be concerned. I understand it was my fault for not changing the email. I don't understand why a service I never wanted or agreed too(Steam Guard), which is entirely optional if you can get into your account to disable it. Why not let me decide if I want that service instead of making me now have to go through hoops to fix a problem that wouldn't even be an issue if they had just given me access when I logged in in the first place?
