Not sure if you're serious, or forgot the joke icon. "$Carrier name is crap!" is kind of a standard line, so it's not like the competition has set a high bar. Walk over, step over it, accept the accolades.
Google's Project Fi. They offer customer service by voice, e-mail, and text chat, within a handful of minutes at most. Samsung? Ehhhh, go talk to your carrier (in person, because anything else is totally rubbish), or at worst Samsung's tech support line (say hi to Josh from India for me!).
