Thanks for the update. I guess we'll wait for the OP's side of the event, but if they don't, then that's that.
Oh wow, did you hurt your shin? Or you slipped and broke your nose hitting floor, perhaps? No? I'm glad. You know, it's quite dangerous to run and jumped ship that fast. Be careful next time, do it carefully and --if you can-- with much grace.

Anyway, it seems the case is done?
Done from BC's side. I believe after confirming my last query to them, whether there is a staff speaking her language being present at the session and informed the security team that the discussion between her and her son was not a simple translating what's asked, but rather leading her to answer details about "her account" [one that she should have a very intimate knowledge of], BC has full right to leave this case and not attending to OP's demands anymore, as it's proven that OP indeed abuses their system.
After their answer, if it's clear and explaining enough, I think the community can agree that this one can be marked as resolved.
