From what I have been told, them seeking legal action is just a scare tactic. To proctect themselves, they do not want their call center location disclosed, nor do they want their "real" corporate office location disclosed.
When speaking with them, tell them you'd like to record the call of your offer. Mention that if such (reasonable) offer is refused, that you will consider you account cleared, and closed.
You mentioned the name Sharon...is she with E-Care?
