Well you're cool, calm, and systematic about it, which will keep any losses under control. If it was a bug, they should credit you back, although that might take a while. I'm sure their IT Helpdesk is drowning with requests, and may need to investigate the system first, but you did the right thing by contacting them immediately to get up higher on their queue. I wonder if there's an escalation email distribution you may be able to find on reddit or elsewhere that can get you faster responses. I've found that to be helpful with my mining services.
