How to cancel Sinopec by mail
Gather your account details
You will need the name and email on the account and, if you have one, an account or customer number. Use exactly the details Sinopec holds, so the request can be matched to your account.
Write the cancellation request
Postbye writes the letter in Chinese from our Chinese template, because Sinopec's address is in China. It opens with the subject line “主题：取消请求 – [your name]” and asks Sinopec to end the subscription, stop all further charges and confirm in writing.
Send the letter by certified mail
Send the letter to the Beijing mailing address shown below by certified mail. Keep the tracking number safe.
Keep proof the letter arrived
It shows the date Sinopec received your letter. Check your next statement: no Sinopec charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Sinopec cancellation letter goes
Sinopec lists 北京市朝阳区朝阳门北大街22号, 100728 Beijing, China as its mailing address.
The envelope is going to Beijing, China, so the postcode 100728 must be on the front.
Your name, address and email appear in a short block labelled 账户持有人, 存档的账单地址 and 存档的电子邮件地址, under the greeting “相关负责人：”.

Before you cancel Sinopec, 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
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.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
