How to cancel 4ukey by mail
Note your account details
4ukey will look your account up from what the letter says, so check the name and email on the account and, if you have one, an account or customer number first.
Draft the request
Because 4ukey is dealt with in Chinese, the letter is written in Chinese (template zh). Subject: “主题：取消请求 – [your name]”. It requests an end to the subscription and to every further charge, plus written confirmation.
Post it with proof of delivery
Take the letter to the post office and ask for certified delivery to 518172 Long Gang Qu. Keep the tracking number it gives you.
Keep proof the letter arrived
File the receipt with the letter. A 4ukey charge dated after delivery is the one to dispute, and these two documents are what you quote.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel 4ukey, 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.

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.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
