I am unable to find my username to login cPanel (i had deleted infinityfree's emails) How to get it?

Hello, @Admin I have lost my username. I want to access cPanel but it requires Username which I don’t have right now. I have checked emails but I had deleted and didn’t found any email. Any method to get a username? Please do response me as early as possible.

My registered email is spreadcraze@gmail.com

If you were able to login to the forum, you probably have access to your client area as well. The username and password of the control panel are listed there for every account.
