Hi,
Do you know for sure that its not going through?
If its only speculation, then maybe wait and see if you get a response.
After a while, if you dont receive a response then maybe try and submit it again but on a different device / browser in case that was the problem.
If you do know for sure that its not going through then id try and submit it on a different device or browser and see if that fixes it. If that does not fix it then check to see if you have missed any information and make sure you complete the anti-robot check.
Thanks.
