How to cancel Banco Santander Chile by mail
Start with your account details
Banco Santander Chile will look your account up from what the letter says, so check the account email, the last four digits of the linked bank account or card and the membership tier first.
Draft the request
Postbye writes the letter in Latin American Spanish from our Latin American Spanish template, because Banco Santander Chile's address is in Chile. It opens with the subject line “Asunto: Solicitud de cancelación – [your name]” and asks Banco Santander Chile to end the subscription, stop all further charges and confirm in writing.
Post it with proof of delivery
Mail the letter by certified mail to the Santiago address in the next section, and keep the tracking number.
Save the tracking record
It shows the date Banco Santander Chile received your letter. Check your next statement: no Banco Santander Chile charge should post after the cancellation date.
