FORMAL COMPLAINT -- told iPad was free, then charged for iPad and mobile service; canceled service and still being charged

This is a formal complaint about a series of unauthorized charges going back to Jan. 2025.

I didn't want the iPad or the mobile service for it. I don't use the line, have never used it, told the agent that on the phone, and they assured me over and over that the iPad was free and accepting it would reduce my Internet bill. I know now that the free iPad offer is a fraud or scam that Xfinity has continued to offer customers, knowing that it is misleading and confusing.  I canceled the service and I'm still getting charged.  I've spoken with live assistants (on the phone and in the chat) multiple times.  I've been told twice that I would be refunded; in the most recent call, I was told I needed to return the iPad to an Xfinity store.  This whole scheme is fraudulent and I am requesting a refund.  Thank you.
