Or, if you don't want to fight this battle in lieu of other tenants, _threaten_ to sue to either force the agency to reveal the name and address of the landlord, or ideally, have them put pressure on the landlord to return the security deposit.
I'm already suing over the security deposit - that's actually an open and shut case. In this case it's not clear that I actually suffered any personal damage so it's not immediately clear whether I have standing in a civil suit.
Did you ask a lawyer-- any lawyer-- before writing the sentence surrounding this word?
I assume the answer is yes. But I also think I remember reading a blog by you where you wasted hours attempting to reverse-engineer some hardware before finally sending it the help flag.
