How to cancel AiBank by mail
Collect the details you need
Have the name and email on the account and, if you have one, an account or customer number to hand. The details in the letter need to match what AiBank has on file.
Draft the request
Postbye writes the letter in Chinese from our Chinese template, because AiBank's address is in China. It opens with the subject line “主题：取消请求 – [your name]” and asks AiBank to end the subscription, stop all further charges and confirm in writing.
Post it with proof of delivery
Address the envelope to AiBank, Beijing, exactly as printed in the next section. Certified mail gives you a tracking number and a delivery record.
Keep the proof of delivery
File the receipt with the letter. A AiBank 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.
Where your AiBank cancellation letter goes
For a letter to AiBank, use 北京市朝阳区安定路5号院3号楼8层, 100029 Beijing, China.
The postcode 100029 belongs to Beijing, China, so this is where the envelope is delivered.
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 AiBank, check these
- 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.
- Check your next statement: no charge should appear after the cancellation date.
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 letter is the formal route: it states the request in writing, carries a date and, sent by certified mail, comes with proof of delivery.
