square enix support

I recently submitted a request to SE support regarding wrongly registered service account. After filling up the form and submitting it i realise i might have some mistakes on the form on which service account. I wanted to cancel the ticket but found no option to do so. Just wondering if request is approved will it take effect immediately without my final confirmation or will an email be send for me to verify pending changes and i have to give final confirmation before changes are made? Just abit worried that they will go ahead and make changes without final consent from me.
Advice pls thank you.
