In the first place you will not find ANY manufacturer prepared to "fix" the device you have. The standard industry practice is to replace the unit, not to "fix" it. And believe me, that's a good thing. Trying to troubleshoot and repair a device such as the KF (or the iPad or a smartphone) is both far more costly, takes far longer, and is a far less reliable approach than simply replacing the unit.
Secondly, I've contacted Kindle Customer Support for the Kindle Fire on five separate occasions. In each case I've reached a CS person located in the US who speaks perfect English (at least as perfect as it gets in eastern Washington.) Use the "Help and Feedback" options on the KF during west coast business hours.
Finally, as already noted, there's no question that some KF units have had problems with the charge port. That's not at all unusual for devices in the first few months of manufacturing. (The early iPads suffered from widespread "light leakage" problems, for example.) It takes awhile to resolve such issues among component suppliers.
But it's also true, as pointed out on this thread, that many of the "charging problems" people have experienced have nothing, whatsoever, to do with faulty hardware (or software.) They stem from users failing to reboot the devices on a regular basis and maintaining a regular charging cycle that prevents the battery from getting "out of sync" with the battery monitoring software. If you check the internet, you'll find the exact same problems are reported for other tablets, smartphones, and even the iPad.
