How to cancel Cablevision by mail
Note your account details
Put the name and email on the account and, if you have one, an account or customer number in front of you before you write: the request to Cablevision is only as good as the details it quotes.
Set out the request
Postbye writes the letter in Latin American Spanish from our Latin American Spanish template, because Cablevision's address is in Argentina. It opens with the subject line “Asunto: Solicitud de cancelación – [your name]” and asks Cablevision to end the subscription, stop all further charges and confirm in writing.
Post the letter
Address the envelope to Cablevision, CABA, exactly as printed in the next section. Certified mail gives you a tracking number and a delivery record.
Keep the delivery receipt
Keep the tracking record with your copy of the letter. If Cablevision 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.

Before you cancel Cablevision, check these
- Look for annual or multi-month plans. A plan paid in advance usually runs to the end of the period you paid for.
- Write well before the next billing date. A request that arrives after it can leave one more charge on your statement.
- If an app store or phone carrier bills you, the company cannot cancel it. Cancel with that partner as well.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.
