Reach Legal Department

Hello, I've had several tickets opened for my account, each being closed with no appropriate action being taken, and no notice. My issue is a refund request due to a service Xfinity has been charging me for, when in reality, it should have been free. It was the Xfinity mobile + internet bundle, where for the first year, any user in this plan should have had a free unlimited line on their mobile device (With the option of getting a free A25). One of the latest tickets that was made by the agent I spoke to online had the written statement that the agent affirming this refund will be provided to me, but it has been closed. I'd like to contact the legal department, as I've tried to submit a "Notice of Dispute" with no response yet. I am willing to provide more information if necessary. Thank you.
