Change name

I have had a launch problem a few days ago saying that the password was invalid, I changed the password to be able to enter the game and when entering the name I had in the account that was Claktur has been changed by default to Coolsten. Since I can not change the name again to my antiguno name since it would have to wait about 20 days, I need you to give me back my name since it has not been a change on my part if not a program error.
