KLM upgrades

I am very upset with what happened in the past 24 hours. I’m flying back from Cape Town to Amsterdam and and checked online. I had a reasonably nice aisle seat. Which are my preferred seats. I decided to upgrade to a front seat like I had on the flight down.As I saw that there were a number of seats at the very front of the economy class still available. After sometime trying to get the apps to work I was able to select the seat I wanted and I paid for it using my flying blue myles.

To my horror I received an email this-morning I received a conformation that my upgrade had been moved to a completely different seat than I selected. I am not at the front anymore, but a but a few rows from the front Although for reasons I totally don’t understand it is called the front seat. The worst thing is that I’ve been put in the middle.

I’m very upset about this and feel royally *****ed over by KLM. You have taken my airmiles , let me select the seat I wanted at the front and given me a worse seat then I originally had been allocated.

This, is definitely the sort of behavior that makes me believe I should find an alternative waytotravel between Europe and Cape Town

To make things worse, I spent a good 20 minutes trying to write a response on the KLM complaints app. When I submit all it can say is oops something went wrong Awaiting your response Regards, Emma Speakman
