How to get a refund for icloud email(Hide My Email)

I created an account using hide my email account. I need to request a refund and they ask me to request using that email. But I can’t send a email using that account.

So how to do that? [email protected]

I have sent an email to [email protected] and they replied just in time. But just create a topic for others as a reference.

Thanks

And I don’t think Cursor needs a proper to trigger a refund.
