How to cancel Edesur by mail
Get your account details together
You will need the name and email on the account and, if you have one, an account or customer number. Use exactly the details Edesur holds, so the request can be matched to your account.
Put the request in writing
Edesur is based in Argentina, so the letter goes out in Latin American Spanish, built from our Latin American Spanish template. Subject line: “Asunto: Solicitud de cancelación – [your name]”. It asks for the subscription to end, for further charges to stop and for written confirmation.
Mail it with tracking
Send the letter to the CABA mailing address shown below by certified mail. Keep the tracking number safe.
File the delivery record
Delivery confirmation is your evidence that Edesur was asked. Watch the next statement or two for any further Edesur charge.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Edesur, check these
- Cancelling usually ends access at the end of the period you paid for, so you keep what you paid for until then.
- Use the same name and email as on the account. A mismatch can delay the request.
- Check your next statement: no charge should appear after the cancellation date.
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.
