To KingCanute ( sorry for the delay)
This was a return flight from Amsterdam to Doha to Kuala Lumpur to Denpasar and back from Denpasar to Doha to Amsterdam.
It was the flight back from Denpasar to Doha, QR 961, that was cancelled. This was a Qatar flight. The mail I received announcing that my booking was cancelled,
gave me the possibility to request a refund
FOR THE VALUE OF THE TICKET TO THE ORIGINAL FORM OF PAYMENT WITH NO PENALTIES OR RTEFUND FEES.
There were no alternative flights offered.
I contacted the customers services of Belgium, the Netherlands and even Qatar. They in essence said all they were there only to manage bookings ....

I booked a cash flight reduced with Avios, i.e. € 730 and 56061 Avios points.
Finally I received a refund for only € 556,85 and no Avios points ...

It is all the more disappointing that Qatar actually send an acknowledgment of receipt that literally says "please be assured that we will respond to your message" ..
