why am i still being billed for services after I cancelled our service

I paid that first bill post cancellation. I didn't have service for the bill I am currently being billed for. How do I get a statement credit for this? 

I cannot help that it took xfinity so long to disconnect the service. I cancelled with 10 days notice til the end of my billing cycle. 

Do you happen to have any unreturned equipment @user_k10yt9? Unreturned equipment would pause the refund process for any credit that may be on the account. Unreturned equipment would result in an unreturned equipment charge(s) ranging from $120-$150. If you still have equipment, it would need to be returned before any refund process begins. More information can be found on our 'What to expect with a refund from Xfinity' support page.
