Rust Activation email - Need admin help

Hi there, So I just purchased a key tonight and when I was creating the account I have misspelt the email address. I only noticed when it said 'We will send a email to your account ‘Email account’. I tried to re-use the key with the correct e-mail however it was saying I’d already used the key which is correct. Is there any possibility you could help me at all. So annoyed, ahh -_-.
Many thanks

Im sure this is just a way to get a free key :O?
