Exp edited and coins taken

So today, I noticed a 'Password Incorrect' message when trying to login.
After resetting my password, I noticed the 200 coins that someone gifted me yesterday for my birthday, were taken.
Also, my exp has been edited to just enough to stay lvl 99 (1,1 bil exp)

Unfortunately I don't have a screenshot of my previous exp, but yesterday (Feb 9th) i was Rank 4 (exp).
I do have screenshots saying my EXP being 100%, but I doubt that would be enough proof. It's not a big problem, as the ranking system was changed so my name wouldn't appear anyway, but it still took me a lot of time to get all that.
Though I still have the large amount of Bounty, I had atleast 6,5 bil exp but I can't prove that.

The latest screenshot i took in a gameroom was on January 24th at 12:10 AM, showing me as Rank 2 (a bit before I got a colored name).
