I know there really is no excuse for bored, bad customer service, but my guess is they have had SOOOO many calls about this issue, that it's become annoying to them too. If Disney would just decide what they want to do and FIX it, we'd all be happier people.
You didn't ask, but I'm going to give my two cents here. We are also two families, and we found for some of the harder to get FP+, splitting up the party into groups of two or three worked better. We just got on the phone with each other on FP+ day and coordinated as we went.
