Apple iPhone IOS IOS 11+ Update turned my phone into a paper weight Nationwide

First let me say that in the entirety of my life I have not posted a complaint on a complaint website but I am so disappointed and really betrayed, cheated and deeply disappointed in Apple. My business and home phone is my lPhone 6S+ I depend on it day in and day out. Overnight it became a very expensive piece of junk with one of the IOS 11 updates. 

 I am a hardworking single grandmother. I bought my 6S+ when the new version was coming out so I could save money. It is the most arrogant and abusive assumption that a single woman with payments on  a house, car, utilities, cards, groceries and more could afford to run out and invest in each upgrade of the iPhone.

My phone was working perfectly and now it barely functions and I am not believing the ridiculous story that it was to help with my battery which was working with no issues. I cannot help but believe that Apple attacked their own customers to make their phone (huge investment for me) obsolete.

Not only does it not function but Siri doesn't work. This means no hands free calling while I'm driving so this literally puts me in danger if I need to call someone while I am driving.

i have had iPods, have two iPads and am on my second iPhone and I love the user friendly navigation but how can I possibly buy ever again any product from a company who intentionally sabotaged their own faithful customers in an effort to force them to upgrade. That is a dispicable, abusive, shocking, and malicious practice.

I love Apple products but will never buy one again.
