I cannot edit a Word document after doing a Window...

I cannot edit a Word document after doing a Windows Update. I called MS Support for Office 365 Business and the person then transferred me to another department. The woman acknowledged that she only dealt with installation issues. Then why was I transferred to her? Anyway, she took access to my computer and saw the problem which wasted my time. She gave me another number to call which I did--twice. The first time the automatic voice recognition couldn't understand me. I called back and was transferred to Support and spoke to a woman who said basically that she couldn't help me. She said that she would transfer me to the correct department. (I found out later from her supervisor that she was going to transfer me to the same department that couldn't help me earlier.) I asked to speak to her supervisor. I finally was able to speak to him. He told me that they don't provide Support for Word! He said that I need to create a case online. So I started to do that and then got to the point of being required to pay for it. I objected because the issue just started after a Windows Update and it was obviously a bug or bugs in Word. He basically said he couldn't do anything to help but I would have to pay first and then the Support person may waive the fee which is $499! I was told plainly by a person at the Microsoft Store that if I purchased an Office subscription, that I would get free Support. So I spent approximately 1 1/2 hours on the phone trying to get Support for Office 365 Business and all I did was waste my time and add to my frustration--and still am unable to finish editing the Word document to put on a Website!

Having hassles like this with Microsoft Support is all too common. I am guessing that by now, I have perhaps spent approximately 55 hours on the phone and also dealing with multiple Office 365 Business issues this year after purchasing it in mid February.
