How to cancel Cybernet by mail
Get your account details together
Before writing, collect the name and email on the account and, if you have one, an account or customer number. Cybernet can only act on a request it can match to an account.
Prepare the letter
Postbye turns the request into a finished English letter headed “Subject: Subscription termination – Cybernet”: close the Cybernet account, stop every charge and reply in writing.
Send it by certified mail
Send the letter to the Irvine mailing address shown below by certified mail. Keep the tracking number safe.
Keep the delivery receipt
Delivery confirmation is your evidence that Cybernet was asked. Watch the next statement or two for any further Cybernet charge.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Cybernet, check these
- If an app store or phone carrier bills you, the company cannot cancel it. Cancel with that partner as well.
- Cancelling usually ends access at the end of the period you paid for, so you keep what you paid for until then.
- Use the same name and email as on the account. A mismatch can delay the request.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

How cancelling by mail works
Subscriptions renew automatically, and a written request is the clearest record that you asked to stop it before the next billing date.
If a charge shows up after you cancelled, the letter and its receipt are what you put in front of the company or your bank.
