How to cancel Ddo Online by mail
Find your account details
Start with the name and email on the account and, if you have one, an account or customer number, so the request to Ddo Online names the right account the first time.
Draft the request
The letter asks Ddo Online to end the account, stop every future charge and confirm it in writing, under the subject line “Subject: Cancellation Request – [your name]”. Postbye fills it in from our English template.
Mail it with tracking
Send the letter to the Woolloomooloo mailing address shown below by certified mail. Keep the tracking number safe.
Keep the proof of delivery
Once the letter is delivered, the date on the receipt is the date Ddo Online was told. Compare it with your statements over the next billing cycle.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Ddo Online, check these
- Check your next statement: no charge should appear after the cancellation date.
- Look for annual or multi-month plans. A plan paid in advance usually runs to the end of the period you paid for.
- Write well before the next billing date. A request that arrives after it can leave one more charge on your statement.
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.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
