Making Changes without the Build Files

I hired a developer who took my money and then never finished the job, never provided me with the files needed. I need to make a text change to the App Store page but Apple requires uploading the Build file again. Any way to either download the file from Apple and re-upload it? Or better yet, make the text change without uploading a file? The only change needed is the text in the app store page, no changes to the app itself. thanks
