I added peacock to my Roku. I no longer have the television or Roku and I keep getting billed. When I go on to the website peacock says Roku controls billing and yet Roku says peacock controls billing. Flip flop
For account & billing concerns, it may be more effective to get help from our Billing team. Though as we review here, it looks like you were in recent contact with our Support team. We'd recommend keeping an eye on your email since they'll be reaching out to you from there. And they would be best able to assist you moving forward.
Major streaming providers like Peacock allow you to subscribe to them directly, or through platforms such as Roku, Apple etc. Whichever one you used; you need to cancel there. It is also possible to be subscribed multiple ways at the same time and receive multiple bills for essentially the same service, so be careful.
