Microsoft, your products and tech support stinks!

I am an irate customer for the following reasons:

1. The calendar in outlook 365 suddenly takes forever to load the details and a 3.5 hour LiveChat to create a new profile did not solve the problem! I WANT THIS FIXED AS IT IS IMPOSSIBLE TO WORK LIKE THIS!! 2. I object to having updates forced on me and I have no option in my package to "choose how updates are installed", hence all my (VERY expensive SA data) is used, rather than the additional data that is available after midnight that I never use, but could if I had the option to set the times for these updates. As a result, I have disabled all updates and stopped them running which is not safe! 3. Samsung's SmartSwitch is not compatible with W10, so I can't sync my devices. Samsung's solution is to downgrade to W7 (?!) and MS says it doesn't sync automatically because my provider uses IMAP but they can't tell me what would work, so as usual, the user is stuck with the problem?!!!!
