Cancellation and Autopay

Hello, 

I am cancelling my xfinity internet and wanted clarification on my final bill. I cancelled at the store today (August 12th) and autopay for the next month is set to automatically pay on the 13th of every month. Since I cancelled before the autopay, will I still be charged for the next billing cycle (even though I cancelled before the cycle ends on August 18th)? I just want confirmation that I won’t be paying for services from xfinity since I already returned the router.
