How do I close all my Microsoft accounts (hotmail. outlook, microsoft) and get out of the dead end loop that everyone is asking about in this community?

I have tried to cancel or close my account starting in outlook. It will ask me to deactivate my acoount, and then ask me to go to billing where there is nothing but this forum. Can I please close all these related accounts? My email is hacked and Microsofts subcontractors want to sell me all sorts of things I don't need. Can anyone help and also fix this problem for the rest of the world?
