When a Word document file is corrupted, then you can try several methods to recover it:
1. First of all, you can try the recovery function integrated with Microsoft Word, as follows:
1) On the File menu, click Open.
2) In the Look in list, click the drive, folder, or Internet location that contains the file that you want to open.
3) In the folder list, locate and open the folder that contains the file.
4) Select the file that you want to recover.
5) Click the arrow next to the Open button, and then click Open and Repair.
The "Recover Text from Any File" converter has limitations. For example, document formatting is lost. Additionally, graphics, fields, drawing objects, and any other items that are not text are lost. However, field text, headers, footers, footnotes, and endnotes are retained as simple text.
1. In Word 2007, click the Microsoft Office Button, and then click Open.
2. In Word 2010, click the File Menu, and then click Open.
3. In the Files of type box, click Recover Text from Any File(*.*).
4. Click the document from which you want to recover the text.
5. Click Open.
After the document is recovered by using the "Recover Text from Any File" converter, there is some binary data text that is not converted. This text is primarily at the start and end of the document. You must delete this binary data text before you save the file as a Word document.

I have had great success with the Word Recovery Toolbox application from http://www.oemailrecovery.com/word_repair.html
They have a free version you can try. I would suggest you run the deep scan in order to get the best data set to look through.
Try also to restore the file using this online service. I found it in Google. https://onlinefilerepair.com/en/rtf-repair-online.html
