I tried the reset password option, which did not work.

The company does not have a customer service email address, which is pretty damn fishy if you ask me. But I was able to find their PR address, and while I couldn't get Gmail to set up an auto-forward option (apparently you need a confirmation code to verify that the forwarding address belongs to you), I can sure as hell MANUALLY forward them with an annoyed 'I don't have an account. Stop sending me email' message -- which, in fact, I have started doing.
