In the future, it would be the best to save the account's information somewhere. Just to let you know, there is some sort of note pad, as you can see here
where you could save it. Only you and the staff can read the information you have saved there. If you take a look at the top of the page, under your username, then you will see that it says "My Controls"; if you click on it, then it will lead you to the page I have linked you.
