How to cancel TWC by mail
Start with your account details
TWC 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.
Write your request
Postbye turns the request into a finished English letter headed “Subject: Subscription termination – TWC”: close the TWC account, stop every charge and reply in writing.
Mail the letter with a receipt
Use certified mail for the 78778 Austin address in the next section, so the post office records the delivery. Write down the tracking number.
Keep the proof of delivery
Once the letter is delivered, the date on the receipt is the date TWC 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.
