How to cancel BYD by mail
Find 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 BYD is the easiest one to set aside.
Put the request in writing
Postbye drafts the request in Chinese, the language of China, with “主题：取消请求 – [your name]” as the subject line. It asks BYD to close the subscription, stop billing and confirm in writing.
Send it by certified mail
Take the letter to the post office and ask for certified delivery to 518119 Shenzhen. Keep the tracking number it gives you.
Keep the proof of delivery
Delivery confirmation is your evidence that BYD was asked. Watch the next statement or two for any further BYD charge.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel BYD, check these
- If an app store or phone carrier bills you, the company cannot cancel it. Cancel with that partner as well.
- Cancelling usually ends access at the end of the period you paid for, so you keep what you paid for until then.
- Use the same name and email as on the account. A mismatch can delay the request.
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
A subscription ends when the company records your request, not when you stop using it, and a letter is the record you can show later.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
