How to cancel Viki by mail
Start with your account details
Before writing, collect the email address on the account, the plan name and, if you can find it, the billing partner shown on your latest statement. Viki can only act on a request it can match to an account.
Put the request in writing
Ask Viki to cancel the account, stop all further charges and confirm in writing. Postbye prepares the letter from our English template, with the subject line “Subject: Subscription termination – Viki”.
Mail the letter with a receipt
Send it certified to San Mateo, United States, copying the address from the next section letter for letter, and keep the receipt slip.
File the delivery record
The receipt dates your request. Look at your next statement for any Viki charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Viki, check these
- Bundles and add-on channels can be billed separately from the base plan. Ask for every line to be cancelled.
- Check the billing date on your statement and send the request well before it, so the cancellation lands inside the current period.
- If an app store, phone carrier or TV provider bills you, the service itself cannot cancel it. Cancel with the billing partner as well.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

Cancelling a streaming or entertainment subscription
Streaming plans renew silently each month, and many are billed by a partner such as an app store or a TV provider rather than the service itself, so the request has to reach whoever actually bills you.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
