trying to delete account

Hello, I don't use reddit... ever, but i figured this was the best place to ask this. I have an old wattpad account i really, really, really want to delete, and have wanted to for years, but have gotten locked out of it because it uses an email i don't use anymore. I have a few ideas of what the password might be, but I have no idea where to start (other than typing in a hundred variations, which I already have started doing)

I was wondering if anyone knew how I could do this? Is there a way that I can get it deleted?
