Today I got a message from Pam. Apparently they had a little chat with Prewire about their performance. Rick handed them a copy of the letter and said "You need to make this right."
Evidently Prewire has decided to refund the cost of the network wiring. I'm still paying for the structured wiring package, but they'll reimburse me for everything beyond that. I won't believe it until I have a check in hand, but... yes, this would go a long way toward making me feel better.
I wish I could have been a fly on the wall for that conversation...
