An SC Upgrade from singles..$1323.00 You can rejoice you may get yours after I have my Avalon..!!! Lol 
Why did it take so long for you to receive a refund? [2 Weeks?]Did they give you a "hard time" with the refund or something?
They probably just skim the subject line in the emails they receive at the moment and assume you're just asking about delivery dates unless it's clear it's a refund request. Setting up a dedicated email address for refund requests would be a good idea.
