This isn't really a good HN story. Companies do this sort of thing all the time, and the comment section is just going to be a predictable rage against the company. There really isn't a connection to any particular HN interest other than the vague fact that the particular charge being disputed happens to be about something electronic, but the story could just as easily be disputes about flower delivery or natural gas service.
