I am not sure about the re-appeal. But this is disgusting, they are just looting people, at least push them a little bit with some sort of notice or something. Ask them to refund and why they are cancelling results. I would categorically ask them to tell me if they have any proof of doing cheating or not? If not then why cancelling.in Saudi Arabia , nothing happened with me , and did you recommend to go for appeal ?
I would at least try to put some pressure, though I understand it is really difficult to go to court or something like that.
