Need help deleting extra account in Teams under same email.

There are a lot of discussion on deleting account but none of them related to my problem.

I have 2 personnel account under same email, and I want to delete free one (one appears to me as free and other connected to my office subscription).

I couldn't find any option to delete that one. When I went to my account there is only shown one but when I open Teams it shows 2.
