Created a store with wrong email(typo) and I don't remember the id used

Its a weird issue. I created a store but due to a typo entered the wrong email id. I added an App and then added credit card for billing. But then I had to sign out and sign in again, but I am not sure what I typed in as the email id. I might have missed a word or wrongly typed one, but cannot recall it. Is it possible to recover the account so that I can update to correct email or should I send a stop payment request to credit card provider?

This is the store url which is password protected.
