In the proccess of updating wordpress.com site to 4.7. I lost all my work.

When I updated my wordpress.com site to 4.7. along with all my plugins. When I loaded my site had I lost pretty much all my work. All my images are unlinked and a lot of the text is missing. It also seems most of the editing features I previously had are missing too. I’ve tried resesting the site and my cache, deactivating plugins and switching to a default theme.
