They have no reason for ruffled feathers. Your response was polite, well-reasoned, and fact-based. No histrionics or ad-hominem attacks. If they do have ruffled feathers it's due to their personality rather than your approach. Well done!
Thanks I appreciate the reassurance. I have a tendency to come across harsh/abrasive/whatever so I do try my best to word things as non-jerkish as possible... Even if I am a little upset about this whole thing.
The person I emailed it to (which I actually ended up pretexting the email with something along the lines: "I don't know if this is the right person to send this to.... but") got in touch with me yesterday to get clarification on what my issue was, stated that they indeed were not the ones to handle it, they are just the middle man, and would attempt to find out who this needed to get forwarded on to in order to resolve my issue.
So now I get to play the run around game until I find out who this specifically needs to be addressed to... This is what happens when your organization is just a tenant of the building, I suppose, and I will just have to keep pressing until it gets to the right person.
