@pedromyahi11Deleting your save game file/4G reserve on your internal HD will not effect your progress if you have been online whilst playing the campaign mode as all is synced with the cloud which is available for each of your games through Xbox Live servers not EA servers. If you play the campaign offline( I cannot do this as my SWBII was purchased as digital download and if I don't login, it will keep asking me to load the disk) then yes EA are right. If syncing is the problem, you may be able to test this by deleting the files from local HD (not everywhere as this will delete them it from the Cloud and anywhere else you have played the game). It will automatically resync with the Cloud file on startup. If it doesn't then we can assume your Cloud file has been corrupted or is missing. If this is the case, all your progress will be lost. Creating a new account will have the same effect, you will be back to the beginning.
You said you haven't started the campaign so all your progression must be multiplayer/arcade - how far have you gotten?
