Being charged for Xfinity Mobile when I didn't activate an account

I'm having the same issue with being charged for years now for services I did not activate. I'm see now that I was being charged all this time. How is it that Comcast can get away with this type of trickery with separation of bills. I had no idea Mobile services get charged separately. I need assistance with getting my money back. My mobile service has always been under Verizon and still is. The customer service person who sold me internet and home phone (which I also don't used) sent me a Sims card that I never activated because I wanted to stay with Verizon so I wouldn't loose all my pics, saved items, etc...already on my phone. I'm thinking about legal action and contacting BBB.[Edited: "Solicitation"] I'm sure Xfinity has done this to lots more unsuspecting people.
