iCloud account out of storage without any data

Hey guys,

My account has been out of storage space for almost a year now. It says I am using 9.2 GB of data in my email, but I do not have any email in any folder or trash. I have contacted apple support multiple times they always tell me they will call me back and never do. It is very frustrating, I get the out of space messages a lot. Is there something I can do to reset my account? Or Is there any Apple dude here that can help?

Thanks
