I called and got a super weird answer. I asked her if we could upgrade my second line that was due on 4/4 early on Thursday. She said she couldn't move the upgrade date, but she could order the phone for me on Thursday.
So I said, "So you're saying that I can upgrade that line at the discounted price on Thursday, and the contract date will remain the same, effectively renewing on 4/4?" She said, "The contract date will be 3/17/11-3/17/13."
Okie dokie! She said I would have to call in so they could approve it at the time of the order. That's fine. Too bad she was clear as mud, though.
