Unusual service from KLM

On a flight from Cape Town to Amsterdam (KL0598) on August 3, 2017 I witnessed a rather bizarre incident regarding the drinks and food service. I should mention that over the years KLM has been my favourite airline, so what happened came as quite a surprise. After departing from Cape Town the food and drinks service for a section of the aircraft was simply terminated without any explanation. After waiting for some 20 minutes and seeing no further activity, I went to the back of the aircraft and complained. Only then was I served. As I regarded this as appalling service I sent two emails of complaint with full details to ********** one on August 7 and again on 7 September. The letter was addressed to Mr Pieter Elbers, Chairman and CEO of KLM. I have not had any response which is somewhat disturbing.

Yours sincerely, Prof W A Richter.
