Whenever I receive bad service from a brand, I typically fire off an angry tweet and hope the company or organisation I'm complaining about notices the blue tick next to my name and takes action accordingly. It's ungracious, makes me look like a bit of a dick, and similar to trying to shift a caffeine-induced headache by consuming more caffeine, it may feel good momentarily but hardly ever works. Enter Resolver, a U.K. startup that's built tools to help you complain the correct way. They include automating parts of the complaint letter-writing process and tracking the progress of your grievance. And now the company wants to take all of the data it's amassed regards what works and what doesn't and apply AI -- their words, not mine -- to make it even easier to resolve issues.
