Refund Support Ticket System Broken

I am unable to request/initiate a refund for COD Modern Warfare II (Unreleased at the moment).

The system to request/initiate refund hangs indefinitely, then eventually gives me an error code, effectively rendering the ticket system useless. I have tried various browsers, computers, different days, but the result is the same.

There is also no way to send an e-mail or have an online chat in real time with Blizzard/ personnel to start a conversation regarding requesting/initiating a refund. I am stuck with a $100 purchase I am unable to refund and would like a resolution. Please help!
