Service cancellation

Hello,

I’d like to cancel my Xfinity service because I’m leaving the United States.

I previously tried to cancel my service through the Xfinity app, but the agent told me that I had already paid for September and that I should contact Xfinity when I need to pay the new bill.

However, I’m leaving the U.S. on September 8, and I noticed that my next billing cycle appears to start on September 13. I would like to cancel my service effective September 8, before the new billing cycle begins.

Could you please help me cancel my service without a phone call? I would also appreciate it if you could confirm that I will not be charged for the billing cycle starting September 13.

Thank you for your help.
