Did my attempt to add a line to my familytalk 1400 plan just add a new familytalk plan?

I just preordered an iPhone 5S as an upgrade to a current phone, and at the end of the order process it listed "No Voice Plan Changes" next to the phone. Yay.

I then preordered an iPhone 5S for my Mom, choosing to add a line to an existing plan, filling out a ton of my personal info (it asked for a driver's license and SSN as part of the process), and then it listed my existing familytalk 1400 plan on one line and another line with other plans. I chose Familytalk 1400.

On the Thank You page at the end of the order process, under a heading of "Rate Plan", is listed "Family 1400…………$80.00". Is this just telling me the cost of my current plan, or that I've just erroneously been led to sign up for a second Family 1400 plan even though I started the process by clicking "add line to existing plan". I'm hoping it's just a confusing bit of feedback at the end of the ordering pipeline, as I should be paying an additional $9.99/mo for the additional line and then $30/mo for the 3Gb data plan, not $80/mo for another FamilyTalk plan plus $30/mo data.

I tried to call apple support, but that's down due to high call volume. And there doesn't seem to be a way to send in an email to support.

Anyone else have this problem?
