How to cancel Defontana by mail
Note your account details
Start with the account email, the plan or product name and the invoice or order number from your latest receipt, so the request to Defontana names the right account the first time.
Prepare the letter
Because Defontana is dealt with in Latin American Spanish, the letter is written in Latin American Spanish (template es-419). Subject: “Asunto: Solicitud de cancelación – [your name]”. It requests an end to the subscription and to every further charge, plus written confirmation.
Send it by certified mail
Use certified mail for the 7560903 Las Condes address in the next section, so the post office records the delivery. Write down the tracking number.
Keep the proof of delivery
Keep the tracking record with your copy of the letter. If Defontana bills you after the date it received the request, you have the dates to point to.
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 phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
