Unfortunately, I found that the best way to resolve these situations is to post publicly on Twitter about what happened making sure to @ the relevant company and # the relevant things. If the support group won't help you, then maybe the PR group can. Basically your attitude has to be "either you give me my $900 back, or I'll make sure this problem costs you more than $900 in bad publicity." The math becomes better for them to give you your $900 back, if they can publicly look responsive to complaints or maybe even get you to take down your post.
