If you enter a wrong or invalid Transaction ID on AmarEvents, your payment request will be submitted but will likely be rejected by the organizer when they verify it against their mobile banking records. You will receive a 'Failed' status notification. To fix it, contact the event organizer directly with proof of your correct Transaction ID, or reach out to support at https://wa.me/8801978431336.
