Hi welcome to JustAnswer, my name is David. I am reviewing your question and will reply ASAP.
Is the data that is unsaved something that you had just added to these documents, or have they never been saved even in an earlier draft?Do you run any live backup systems for example Time Machine?What software are the documents in? Some software might have cached versions, and that could be a way to get some or all of the data back if they have become corrupted.Thanks in advance.
No problem. Unfortunately the nature of this question is you can't give a direct answer to it, and so it becomes a question of how valuable the time and money are toward the value of the data in the documents. You can contact JA customer service regarding the refund, have a nice day!
