No, don't keep e-mailing them. In fact, ignore pretty much everything Gwazi said. He's just bitter because he got caught cheating.
If you keep e-mailing them, then instead of seeing your e-mail and taking the time to fix it, they instead have to read 2, 3, 5, or however many e-mails from you. This will probably take them more time than simply addressing your issue (and probably makes them upset at you and puts you at the bottom of the priority list).
The Multi-accounts activity has been slow lately, as Ranma mentioned, and patience works better than spam.
