After an awful customer service experience, you want to vent by writing it up on Trustpilot. But no one wants to read your fifty line rant.
So how about a simple scoring system, so you can say, for example:
"Cooperative Bank (to pick a brand at random... not really)120 minutes time on phone10 days to resolve my problem225 Marks of Shame."
This way people would get a measure of the severity of distress caused but don’t have to relive it. The Marks of Shame would accumulate rather like the way they mark Olympic ice dancing, with each move given points for technical merit and artistic impression. For example,
- Each hour waiting on phone: 25 points
- Each time The Four Seasons starts again: 10 points
- etc... I'm sure you'll have your own favourites.
