The best advise is already mentioned above !
The real issue is probably mentioned in the fine print, shown when you subscribed : they (paramount) give you content that you want ... but they give more then that : content that you don't want.
They said : you also paid for this non-wanted content (actually : you want it, as you accepted the fine print), and we (paramount) pay engineers that take care of the 'you will see what we send you, no matter what' (yep, you pay them to make your life ... let's say : less easy ?!)
So : the stop paying them - or upgrade from 'Plus' to 'Gold'.
If I was working for paramount, and they asked me - with a nice pay rise as a reward : make a system that blast adds all over our customers screen, I would make something like this :
This token frees up the 'right' to see some more content.
Now, when you block this add, .... you block everything.
(I'm just inventing this of course).
True, pfBlockerng can do a lot for you.
But it's not a activate-it-and-forget-it tool. You have to check it, and worse : understand what it does, why it does what it does, and what it can't do.
Sometimes the simplest solution is also the good solution ;)
edit : whitelisting the IP of the device you are using paramount is also 'a solution'.
