Hello, farovertheforth!
Thanks for posting. We would be happy to look up your old account to make sure it's been cancelled and settled, so go ahead and click here to send us a private message.
In your message, please provide your name, phone number, email address, and the best time to reach you. You can expect a reply within two business days, so keep an eye on the little blue envelope icon in the top right corner of your screen. As for the GoPhone SIM with the other number that you don't need, as long as you don't use it, it should just deactivate and cancel the account all by itself.
In the meantime, feel free to message me with any other questions or concerns.
