I had a flight cancellation some months ago, my itinerary was mixed LX/LH but ticketed on LH. It was the first flight of the itinerary and was cancelled due to a technical issue with the aircraft. A ticket agent at the airport cancelled the rest of the itinerary as it was not useful for me to travel next day.

For months I have been trying to get LH to refund the ticket cost. My understanding is that if the airline cancel a flight, I am entitled to a full refund if I choose not to take a later flight (correct me if wrong on that one). Telephone agents agree with me, but so far I've only been refunded taxes minus a service fee.

Any suggestions how to tackle this impasse with the airline before I have to pay someone to deal with them?
