On the other hand, I can tell you that whatever they did, I'm not getting the hot spot and bad battery life that I used to get.
So, I have reason to question what you believe: that they're giving more of the same and that this too will fail. I also have reason to question that a CS rep reading a script for twenty cents an hour has any knowledge of the situation, so I would never expect anything from a script monkey.
I also know that companies like LG wouldn't reveal their own flaws if they didn't have to.
I know that back in the day, Honda used to have "goodwill warranties". In particular, they know more about their product than anyone, and they knew when some part failure was unexpected abnormal. If the custom asked for accommodation, they'd give it.
Apple does the exact same thing today.
None of this is unusual in the business world. So what if you have to ask for the help instead of having it spoon-fed by the manufacturer? Welcome to life, where you have to ask for and go after things you want, instead of having them handed to you. Yes, it would be nice if these parts didn't fail; but life isn't perfect, and parts do fail. So what if you have to ask for help? Get off your high horse. It's called life.
