I had an issue with one of my apps and went through the appeal process. The issue was that had (in Google’s assessment) misrepresented my app. I went back and read the policies carefully and changed the description and the various privacy policy disclaimers. My app and account were restored. The emails google send are vague. Take your time and read the email and all of the links they provide carefully and make sure you address all possible issues. Avoid arguing or simply resubmitting the same information.
Best of luck.
