Change invalid Email

I had just reset all my account information through support tickets.
But i was so careless to gave the staff an invalid email.
Then they closed the ticket and sent my new psw to that email and I can't get it.

So I just want to ask can I change it to a valid email again?
Because I had waited for at least 30 hours and no replies.
I have Security answer, IP address, Paypal transaction IDs, etc.
I just dunno the password.

It is so important to get my account back earlier for GM tournament.

Please help me !
