Deleted Saves, Test Server on XB1 questions

[Neptune443]

I've been playing since the game launched and had saves with 230 days on it. I thought i would download the Public Test Server and give it a try but i didn't realize it wouldn't be a seperate game but it would become part of my normal game. So i decided to be safe i would get rid of the PTS version and go back to the old version. The xbox test server page said unistall the game, reboot the xbox, then reinstall. i did all that now my saves have reverted back to around September 9 when i was at 180 days played. All my work over the last 2 months is gone!

How do i report this or file some sort of claim?

Is this fixable or am i just screwed?
