How to cancel Mozart by mail
Get your account details together
Mozart will look your account up from what the letter says, so check the account email, the plan or product name and the invoice or order number from your latest receipt first.
Draft the request
State plainly that you want the Mozart 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 the letter with a receipt
Send the letter to the London mailing address shown below by certified mail. Keep the tracking number safe.
Save the tracking record
File the receipt with the letter. A Mozart 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.

Cancelling a software or app subscription
Software plans are billed per plan or per seat, often yearly, and the app store version is billed by the store rather than the developer, so the request has to name the plan and who bills it.
A letter is the formal route: it states the request in writing, carries a date and, sent by certified mail, comes with proof of delivery.
