Some more emails from Continental.

08/30/2011 Reply from Continental (From: customerrefundservices@coair.com, RefundsHouston@coair.com in signature) to approv refund
08/30/2011 Reply from Continental (From: custo@coair.com) for refund request submit via web on 8/15 (not yet received voucher mentioned in the email)

So, it looks like this is what happened.

Sent 8/5 -> Reply 8/25 (email to RefundsHouston@coair.com)
Sent 8/15 -> Reply 8/30 (submit via web)
Sent 8/23 -> Reply 8/30 (email to customerrefundservices@coair.com)

It does seem that either way works at the end of the day. (Though RefundsHouston@coair.com doesn't return any acceptance, while web UI and customerrefundservices@coair.com does. So, I still recommend web UI or customerrefundservices@coair.com over RefundsHouston@coair.com)
