Not able to delete created organisations in MS Teams

I'm having the same issue and it is really frustrating as it hinders me in opening documents, meetings, messes up the login and all. I have also been in touch with so called support and they are perhaps trying their best. However they also seem a bit pre-defined about what my issue is and how to solve it. Not really fixing it. 

One thing that came to mind was the fact that the organizations I am having issues getting rid of is organizations that was attached to my email when I only had a private office subscription. Or even no, but registered online.  Now I have business, but the organizations can't get away. Could it be an issue that is coming from my personal account and has transferred to my business account?
