Solved

Some of my coins were "stolen"

I tried to update my cars appearance before a race just the colors it cost 4 coins but it took 10 and never changed the cars appearance 

Hello,

No tokens have been deducted for the livery change (which never happened). 10 tokens were deducted for the manager name change. There is a bug that does not show the cost of the operation.
You changed your name is it said it could be done for 0 tokens, but in reality it is not. The Name, Surname, Nationality change has a cost of 5 tokens each.
With that said, I have returned the 10 tokens to your account.
We apologize for the inconvenience.

Regards

Oh.... i thought it was weird that it said no coins for the name change but I was just happy that when I saw 0. thank you for giving the coins back
