One of my jobs is working in retail and I can't tell you how many people want to you to think an issue is that staff member's individual fault.
Given this case, where they're probably fielding a number of calls from people with a variety of issues, I figure pointing out I was polite was probably a point worth making - unless I misread your emoticon!
One of the PC threads talked about chargebacks after missed delivery dates. The TRU email specifically mentions Pre-order for October delivery, so hopefully that will assist, even if no-one has a copy of the item page online.
Also, I was offered merchandise (of my choice) worth the price I paid, but given the interim of not having an update on the actual item in question, I declined. Well aware I'm rolling the dice on the $120, but figured it was worth a shot.
