I got charged 375 aed for a a visa that I can get for free on arrival to Oman. And when I made the complaint the answer was ( it's mentioned on the internet that it's free and you decided to do it with us! What a joke! Unprofessional. As they ask you about all details before applying they should come back to you with an honest answer if this application is chargeable or not. Not getting every single opportunity to steal people money!
