Paramount+ Xfinity Frustration

I am beyond frustrated with this also.  I was charged for a year of Paramount + that I didnt want. I noticed the charge 10 days after it showed up and went into a local xfinity store and an employee said he will put in a request to cancel and i should expect a full refund. but cannot log in to watch anything. I have spent hours on numerous calls with Xfinity.  I was told this is a Paramount + issue and i had tk contact them. When I spoke to Paramount + the woman was frustrated Xfinity "keeps telling people this". I gave her my information and of course she cannot find me in their system because...it is billed through Xfinity and thay they need to fix it. I called Xfinity again and finally put me on hold to talk to a supervisor. This guy said it is a Paramount + issue and said I needed to call Paramount+. Reading online how to cancel using the Xumo box, i tried to access Paramount +.  However when i do, when you are on Paramount + activation page, it does not have Xfinity as a supported provider. I am working professional and I dont have time to keep calling people. So you are charging me for something I dont want...and you both say its the others problem. Let me say this, I wont pay for something I dont want and won't use.  This is ridiculous that there is not a plan in place to fix this.
