Lufthansa could reasonably offer non-full refund - refund 90 % or 95 % or 98 % of the ticket fare for full fare flexible ticket cancellations or changes. But if Lufthansa clearly promised 100 % refund/change unlimited number of times then Lufthansa should be held to the language, good faith or bad faith.
