As a user, it's not very clear how to complain on the App Store. I did it once and got a refund from Apple, because it was an obvious case. But recently I bought an app that was not obviously problematic: it was meant to do some things, cost a few $, and did indeed do "some" things, however the app actually felt like a tutorial code (maybe even one from Apple) implemented and pushed to the store. Just like that, almost no features, no design or quality. It's difficult to complain, but I clearly couldn't know from the store itself.
