What's Wrong?

I'm a $200/month Max plan subscriber. Yesterday morning (18th April) I had $130 of extra usage budget in my account.

During the day, Claude Code used up my entire "Extra usage" budget of $130, because Sonnet was stuck on 1M context version without me realising. There was no indication that it was using money instead of my Max plan. In addition, it was rather confusing because the new Opus 4.7 model has 1M context, but selecting that does not deplete my extra usage budget.

Please can you reinstate my $130 of extra usage? I've tried clicking the "Get help" button on your site but it does nothing.
