l application payment is complete. but, my details are not submitted.
If you have paid the fees for application then it can only get submitted if you have filled your application and its submitted. Now if the information details aren't showing then you can wait for some moment as it can be due to some issues regarding the server. Apart from this if its not improving then you should contact the organizers. The details you will get on the official website where you have filled the application form.
You don't provided necessary details about the purpose. As a result, we can't conclude all this.
I hope this helps.
