How to cancel Kencko by mail
Start with your account details
Check the name and email on the account and, if you have one, an account or customer number before anything else. A request that does not match the account on file at Kencko is the easiest one to set aside.
Write your request
The letter asks Kencko to end the account, stop every future charge and confirm it in writing, under the subject line “Subject: Subscription termination – Kencko”. Postbye fills it in from our English template.
Mail the letter with a receipt
Take the letter to the post office and ask for certified delivery to 19958 Lewes. Keep the tracking number it gives you.
Save the tracking record
Delivery confirmation is your evidence that Kencko was asked. Watch the next statement or two for any further Kencko charge.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Kencko, check these
- Check your next statement: no charge should appear after the cancellation date.
- 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.
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
Most subscriptions keep billing until someone tells the company to stop, and a dated letter is proof that somebody did.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
