That sounds really frustrating. I can definitely try to help. Since you've never been able to access the account and you're getting the same error with Google, GitHub, and Discord sign-ins, it sounds like something went wrong when Vapi created your workspace on their end. If you can share exactly what you've tried so far and whether support has given you a ticket number, I might be able to point you in the right direction or suggest a workaround while you wait.
