When it comes to putting pen to paper to complain to an organisation or individual, there’s a fine line you have to walk.
On the one hand, you need to clearly express your upset at whatever the cause of the complaint was, be it bad service, a poor quality product, a billing error or simply a failure to deliver at all.
On the other hand, it’s important to remain calm and objective. You don’t want emotive language or a hectic structure to cloud your intentions or undermine your sincerity.
