App not deleting



Our devs created an app using an old twitter account - just for testing purposes - to enable “logging in with twitter” type of functionality in a mobile app. We have since deactivated that twitter account, however it seems that somewhere in Twitter world the app name still exists and I get a validation error now when I try to create a new app with the same name (app of that name already exists).

Is there some lead time on deleting an app or something? Any way I can reclaim that original app and delete it?
