I sympathize completely. But there is, at least, a work around.
Try removing the channel via the official Roku remote app on an Android/iOS phone/tablet connected to one of the Rokus on your account. At the bottom of the app's home screen, click Search and do a search for the installed channel name. On the resulting screen you should get options to Launch the channel on your Roku, or Remove the channel. I've never tried to remove a subscribed-thru-Roku channel (I haven't had one for years, and this may give you an idea of one reason why) but others have reported this works with active subscriptions through Roku.
This worked for me also after many useless chats with Roku support . I had the CINEMAX ROKU app stuck on my tv with no delete option This is something they should teach all support staff . I downloaded the Roku app on my phone . Logged into my account , i then connected my tv to the app on my phone hit renew subscription on my phone . The app updated on my tv and asked if i wanted to subscribe . It now has the delete option that was not available before . I deleted the app and then verified with Roku the subscription was still cancelled . I begged Roku support to activate the subscription then cancel so i could see if the delete option returned and was told no every time
