Xfinity Mobile Service [Edited]

I want to report Xfinity Mobile Service is a total [Edited: "Language"]. I was persuaded by a client support that I can freely open a new mobile service and I won't get charged if I don't use it.

It turns out that even I don't use the mobile service/SIM, it still charge me.

The first crazy thing is that, in my xfinity account, I could not find any bill history of the xfinity mobile record. I only figured this out when I recently reviewed my credit card report and found this bills record.

I also find from my commercial email folder that xfinity mobile keep charing me.

Second crazy thing is that, I last week talked with an agent that I was sick about how xfinity mobile is doing to me. He told me that he did verify that I have no bill record of the mobile service in my account, but they can't refund me simply because they assume I need to turn this service off.  How the [Edited: "Language"] can I be aware to turn this thing off if I don't see any bills in my personal xifinity account?

Third crazy thing is that after my last week conversation with the agent, I thought that my xfinity mobile service is cancelled as he promised. Guess what. They still continue to charge me on this????! 

At this moment, I can't believe in this company anymore, [Edited: "Inflammatory"]. They [Edited: "Inflammatory"] starting a service, charge me for the thing I did not use, and even the agent [Edited: "Inflammatory"] to me about canceling the service. How the [Edited: "Language"] can I get rid of this company, that's insane!!!
