Account missing from authenticator app

Question

Hello, I have 2 accounts with Microsoft but only one account appears in the Authenticator app. Unfortunately, my 2 account has a 365 Family subscription. I have no access to it. When I log in with the email, I am referred to the authenticator app. I tried with password, but unfortunately forgot it. Can't reset it because of 2 factor verification. I have receipts at home that I have paid 365 Family to show that it is my account. Specified recurring direct debit and now can't change anything because I can't get back into my account. It's a vicious circle. Please help me. Yours sincerely, Jacek Matuszek
