Hello Amal,

Thank you for reaching out and I am happy to help!
When you purchased the W3 Total Cache Pro and a subscription was created, you accepted the terms and conditions:

By ordering, you are agreeing to our complete Terms of Use. You authorize us to charge your card now and at the time of your renewal annually. You can cancel this subscription at any time by e-mailing customer-support@w3-edge.com.

The Renewal reminder email is sent to the email address used for subscription (In your case, the email you submitted for this topic) seven days prior to the renewal. The email will arrive on June 25th or 26th, depending on the timezone
Do you need to update the billing for the next update?

Thanks!
