I've also been locked out of my Origin account for the last week. I submitted a ticket last Saturday, and have received absolutely no response. If I check "My cases" on the help site, the "last updated" date on it keeps getting new timestamps, but I haven't gotten any emails, nor can I see any updates on the help site itself (I can't even see the info I originally put into the ticket, so I'm not sure if that's on purpose or if the site is broken). I've checked spam folders, just in case, but I haven't even gotten the confirmation email that they received my case (though it's in the list of "my cases" on the site). I feel like any info on this ticket is disappearing into a black hole.
If the ToS team wants more info from me or anything, I'm happy to provide it, but I sure hope they're not asking and thinking I'm ghosting them, since I'm not getting any messages.
