Many App Store customers literally do not know that they can request a refund, or how to request one. App Store does not even have a clear refund policy. You see a lot of reviews for scam apps that say "I want a refund!" They just don't know.
App Store customers assume, naturally but unfortunately mistakenly, that app developers have the power to grant refunds. They have no idea Apple itself is the sole source of refunds. You would think that Apple would put a refund link in the ratings/review area of the store, but nope.
Well, that's the thing, isn't it? The app store (any app store) which has a review process and takes a great cut of revenue, should stand for quality and safety. Here, that's clearly not the case.
For another example, see Amazon problems with fake products.
Both Apple and Amazon are large enough and have so much money that you'd think they could spend some of those resources on handling the problem. Perhaps they do, but appears not.
Fuck, if any other company would be able the provide their logistics, I wouldn't drop a dime again with them.
