Ok I will ask them by web forumThat's exactly why I am telling you to send a copy of the email acknowledging the receipt of application so that they understand that you did send an application but they failed to receive it maybe due to a technical issue. That is the only way as I see it, to establish that you have actually sent an application, or you can send a screenshot of the pr online application portal that shows the application status as submitted with the corresponding date and time of application submission.
