Please cancel HBO Max

I need an Xfinity billing representative to cancel my HBO Max Standard subscription, which is billed at $18.49 per month under StreamStore.

I've already attempted to cancel through Xfinity's subscription management page, but HBO Max isn't listed. The page only shows Peacock Premium and redirects me to an offer for equipment.

Please cancel HBO Max directly from my Xfinity account. I do not want to change my $79/month internet plan or my complimentary Peacock Premium subscription.

Please confirm the cancellation date and that the $18.49 recurring charge has been removed.
