How to cancel hello piano by mail
Start with 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 hello piano names the right account the first time.
Set out the request
Postbye turns the request into a finished English letter headed “Subject: Cancellation Request – [your name]”: close the hello piano account, stop every charge and reply in writing.
Post the letter
Send it certified to London, United Kingdom, copying the address from the next section letter for letter, and keep the receipt slip.
Keep the proof of delivery
File the receipt with the letter. A hello piano charge dated after delivery is the one to dispute, and these two documents are what you quote.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel hello piano, 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.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
