I have to say for all the people complaining but still staying with Amazon, there's a simple solution that will force their hand if enough people act:
Stop buying from them.
Personally I cancelled my Prime subscription because no service is worth enough to me to force other human beings to pee in bottles to avoid work breaks for fear of being sanctioned.
[cancel prime membership]
...
"do you want to terminate your membership?"
[ask me later][keep me signed up][terminate]
...
"you'll lose [x], do you want to terminate?"
[ask me later][terminate][keep me signed up]
...
"but even shipping will cost!"
[keep me signed up][ask me later][terminate]
...
you're now unsubscribed
[sign me back on][ok]
