You probably shouldn't go on the same way otherwise the system may follow the ticket rules and if non refundable you will lose the money. I guess you have to use the refund form to process "manually" the refund: https://www.omanair.com/id/en/manage...gs/refund-form
and explain in the comments that you have right for full refund due to involuntary schedule change.
Then it is your decision whether still book with them or not. It is just my suggestion off course as I didn't have the same problem. I hope you can get your money back, good luck.
