Cancel an on demand order

I am sorry for the delay. I know when my dad visits he will not realize the movies or shows he is wanting to watch are things I have to pay for. I finally set up the pin to prevent accidental purchases.I would highly suggest adding a purchase pin onto your box/ boxes to prevent unwanted movie and show purchases and rentals- make sure you add to all your boxes if you have more than 1.

I also set up Xfinity Text Alerts to get a text message every time a movie or show is rented. You can view the link: https://www.xfinity.com/support/articles/comcast-text-alerts to set this up too!
