Hello Tomas Lundstrom,
Microsoft Q&A is a community forum for technical questions, so we don't have visibility into existing support cases or the ability to resume one from here. To pick your case back up, you'll want to go back through the same channel it was originally opened in.
The most reliable route is heading to https://support.microsoft.com/home/contact, signing in with the same Microsoft account you used when the case was first created, and choosing Contact Microsoft Support. From there you can request a chat or callback and reference your case number so the agent can pull up your history and continue where the previous one left off. If you'd rather not go through the website, the Get Help app on Windows does the same thing — just hit Start, search for "Get Help," and request support from inside the app. And if the original agent gave you a direct callback number or a scheduled time, that's usually the fastest way back in.
I hope it gets wrapped up quickly.
