How to cancel Cer by mail
Gather your account details
Put the name and email on the account and, if you have one, an account or customer number in front of you before you write: the request to Cer is only as good as the details it quotes.
Write your request
State plainly that you want the Cer account cancelled, further charges stopped and a written confirmation sent to you. Postbye sets this out in a ready English template (“Subject: Cancellation Request – [your name]”).
Mail it with tracking
Use certified mail for the L3 9LQ Liverpool address in the next section, so the post office records the delivery. Write down the tracking number.
Keep the proof of delivery
The receipt dates your request. Look at your next statement for any Cer charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Cer cancellation letter goes

Before you cancel Cer, 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
Most subscriptions keep billing until someone tells the company to stop, and a dated letter is proof that somebody did.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
