10 days without being able to reinstall

Why are call backs not possible 24/7?
Why are they only between 5am and 4pm?
Why is ms365 completely incompetent (chat)?
Why is ms365 a complete con?
Why will no one at ms365 support explain how one can be sold an annual subscription only to be told halfway through that Windows 7 is no longer supported (yet it worked for 7 months)?
Why is chat technical support incapable of escalating to a supervisor after 12 hours of chats?
