The mobile carrier that I use has an app on the App Store that subscribers can install in order to view their subscription, change subscription plan, and view past and present bills/invoices. The app itself is pretty good, it's snappy and easy to use. Only shortcoming is that they have a widget that comes with the app but the widget doesn't work and they have been aware of this for a long time without fixing it.

Anyways, I was looking at the reviews and most were positive. But then there was one review that stood out. A one star review, and get this – the review was complaining about something totally orthogonal to the app itself. They were complaining about the prices of the plans the carrier is offering. The pricing of the plans that your carrier is offering is not relevant to managing your plan through this app.

These kinds of irrelevant complaints are sure to show up in reports too, like you say. But let's hope that the amount of those will stay relatively low.
