How to cancel Universo Net by mail
Start with your account details
Put the account number, the phone number or service address being cancelled and the name on the account in front of you before you write: the request to Universo Net is only as good as the details it quotes.
Write your request
Universo Net 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.

Send the letter to the CABA mailing address shown below by certified mail. Keep the tracking number safe.
Keep the proof of delivery
Once the letter is delivered, the date on the receipt is the date Universo Net was told. Compare it with your statements over the next billing cycle.

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 phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
