Badass Rank and keys lost

Hi, I just lost all my Badass Rank levels, tokens and bonus stats and all of my chest keys. I am playing on Xbox One and lost all this due to an internet error, I opened the game and as soon as the game tried to sync my Xbox data I got an error, I tried again and logged into my character and once I loaded into sanctuary I noticed that all that I mentioned above was lost, can you guys please help me?

Ps: My level, career progression, money, skills, eridium, guns and all on my account keep the same, except what I mentioned.

I also seem to have lost my Badass Rank, Golden Keys, and some Quick Change and vehicle skins for Borderlands 2 on Xbox One… Please help!
