Have you ever bought something that you thought was special, only to find that it was less than spectacular when you got it out of the box? Or had a piece of machinery or technology not deliver the performance you expected?
The outcome of this is called buyer's remorse and in some cases you have to put up with it, as caveat emptor (let the buyer beware). But when there are clear cases in life where we experience failure to deliver by products and services, we have the right (and in my view the "duty") to return the product or complain about substandard service. As a consumer, this right is backed by the Consumer Guarantees Act and the Fair Trading Act.
I never used to complain or make a fuss until I learned negotiating skills; from this point forward I have always alerted producers of products and providers of a service to their shortcomings. And, the truth is, if you or your team are providing low standards of service, you won't know unless you are told.
I have written about courier companies who astound me by delivering when it best suits their timetable rather than in the fastest possible time.
As another example of shortcomings, on one occasion we stayed in a reasonably well-known chain and were allocated a room which in no way matched the website photos.
