Many of Oman Air customers have faced, are facing, will face some or all of the problems below. 

All the problems reported are merely the ones I have faced myself and backed by phone recording and email evidence. 

1- Unable to update flights, view the correct information about my flights online. 
2- Hours on the phone trying to get hold of a customer services representative who will always refer you to a different number, department or ask you to do it online (which is what you are calling about not being able to do)
3- Calling different office, internationally with high call costs, results in the same as number 2
4- Emails are ignored, refund requests are ignored, and formal complaints are ignored. When they are not, they are replied to with automated messages, or useless guidelines.
5- If you are lucky enough to get a promise on the phone, that is completely ignored if you are lucky enough to get an email 2 weeks later.
6- Oman Air has cancelled flights without notice, some notices delivered 24 hours AFTER the flight.
7- Conflicting information provided. 
8- No respect for the client, their time, money, nor effort. 

We demand our money back. Never again Oman Air!!!!!
