Last month I paid my bill without examining the invoice.
I checked it today and found a $5.99 charge for Jojo Rabbit which I presume is a kid's movie. I did not knowingly buy a movie of any kind and certainly not a child's flick. I'm 91 and my wife is 88. Neither of us are in our second childhood --yet --. It is possible that in checking the many shows provided by Xfinity, I or she could have hit a wrong button. Please remove this charge and give a credit for it next month.
If an employee doesn't help you here in the Forums, contact one of their Billing reps and ask them to issue a credit. Call them at the phone number on your bill or 1-800-Comcast, use one of the options at https://www.xfinity.com/support/contact-us, or visit a Service Center or Xfinity Store if one is nearby (check locations and hours at https://www.xfinity.com/support/service-center-locations/).
In addition to getting the billing corrected, consider setting up a Purchase Pin on each of your cable boxes/DVRs and in the Stream app and web portal to prevent this from happening in the future. See https://www.xfinity.com/support/articles/parental-controls-non-x1 and/or https://www.xfinity.com/support/articles/x1-parental-controls-turn-puchase-protection-on-off and/or https://www.xfinity.com/support/articles/x1-manage-tv-settings-online.
Always check your statement each month. Skipping it tends to be hazardous to your financial health!
