KLM Royal Dutch Airlines Customer Service is horrible

I have been a flying blue member for many years now and have requested many vouchers over that period. Due to work reasons, I was unable to make my recent flight booking (23rd Jan 2024) and as usual wanted to request a voucher. I did so on the 6th of Jan 2024, the website only allowed me to request a refund , which I did under the belief it would lead to a voucher.

I have been on the phone with KLM services since the 6th of January, I’ve been placed on hold, the phone goes dead and nobody calls me back after they said they would.

They don’t assist until the refund has been paid, and then tell you that the refund has been paid already so they can’t do anything.

I have lost over R11 000 on this ticket (I was refunded roughly R2000 on a R13 000 ticket) and all I wanted was to change the dates of my flight.

KLM don’t seem to care, even though I’m a loyal Flying Blue member. This is the last time I fly KLM. I am appalled by the horrible service I have received and the lack of professionalism.
