I got the number change to go through. That means I'm not the same member on these forums anymore, apparently, so I can't mark an answer (mine) as correct.
For those of you in the future, I had to chat with a support agent to resolve the issue (kind of). Click the "Chat with us" button at the bottom right of your dashboard. I was attempting to transfer my old number from Cricket. When I told the agent about not entering my PIN, they said that the number change was going through from what they could see. It had been a week at that point. They say that mobile numbers take hours and that landlines take 2-10 days. So I guess I was just being impatient, and not all mobile numbers are considered as such. As for not entering the PIN into the form, it seems it didn't matter all that much. A bit anticlimactic of an end, but glad to finally have the issue resolved.

I had to contact chat again to resolve the issue of not being able to receive calls. The agent told me to dial *73, which according to the Internet disables call forwarding. I don't know about that, but then I was told to dial (888) 844-7095. I robot told me to enter the PIN they needed, and once that was done, it was a couple of minutes of waiting before I could finally receive calls on my phone.
