Terrible service and no option to cancel, don’t sign up

Enrolled in YouTube TV with my Roku and found my current provider PlayStation Vue much better in terms of variety of options and navigation. Then went to cancel and it says to visit the website on my laptop which is terrible and doesn’t work. Then tried the app but it doesn’t work either. Then tried website on my iPhone and it too doesn’t work to cancel. I tried going to Apple subscriptions but it doesn’t show. I’m going to have to dispute the transaction for the first charge and cancel my card and get a new card to make sure I’m not charged again. So I’ll have to change all my other recurring stuff like Netflix, Spotify and PS Vue that actually work like they’re supposed to just to cancel the YouTube tv.

PS the developers suggestion below doesn’t work
