Trying To recover old account

Hello, recently I've been thinking of this game and wanted to try it out again. I can't remember my log in details after almost 10 year but I have paypal receipts emails dating back to 2014/2015 when I last played. I canb't even rememeber my character names to look them up on the highscores to see if my accounts are still there. If anyone could guide me in the right direction to switching my email and getting my account that would be amazing.

Edit: thinking of this username one of my accounts is purpsurp hopefully that helps prove it hasn't been logged into in almost 5 years and I'm just trying to get it back.

Another is ^FY^Ee^2

Hey, could you please PM me on Discord? I'll try to help you as much as possible, ommadawn147
