How to cancel Telsur by mail
Collect the details you need
Telsur will look your account up from what the letter says, so check the account number, the phone number or service address being cancelled and the name on the account first.
Prepare the letter
Because Telsur 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 the letter by certified mail
Use certified mail for the 5090000 Valdivia address in the next section, so the post office records the delivery. Write down the tracking number.
File the delivery record
Once the letter is delivered, the date on the receipt is the date Telsur 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.

Telsur takes its post at San Carlos 107, 5090000 Valdivia, Chile, which is where a cancellation letter belongs.

Cancelling a phone or internet plan
Phone and internet providers tie cancellation to contracts, equipment balances and notice periods, so the request should name the exact line or service and ask for a final bill in writing.
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.
