Edited for clarity.

According to this refunds are permitted in certain circumstances as are changes (Reissue) in spite of the summary statements whilst booking saying that it was not possible.
But they may differ from destination to destination. Exactly what they are from your destination you need to check.
Note that the rules for changes/cancellation change from screen to screen in the booking process.
