I bought air ticket thru mytrip from Islamabad to Split Croatia for 02 July, and return ticket for 18 July. I bought Flexible ticket. Due to circumstances I need to reschedule my return trip from Split from 18 to 21: July. I tried to communicate with mytrip agent who told me to ask for reschedule to Qatar airways. As I could them they referred me back to mytrip. Since than I can't get them on phone. I waited for 50 min on automatic secretary.
