please understand that airlines here are plagued by people wishing to have a flight to somewhere booking every conceivable flight to make sure thy are covered whenever they wish to fly. Until recently airlines accepted this but lately decided to impose a penalty of I think 100Qr for changes. What is that compared with the loss of a holiday for someone else? Best advice is complain loudly. I've had the police called to stop me but it paid dividents, I got an alternate flight. Qatar Airlines is wonderful in the air, best trained flight crews around, on the ground maybe not so good in customer relations, defensive shields go up at every complaint! Persevere and it will be ok!
