Identity Fraud/Unauthorized Xfinity Mobile Account Added to My Internet plan

Hi,I am facing a severe case of unauthorized service and identity fraud on my account .I only signed up for Xfinity internet .I have never ordered ,authorized ,or received any Xfinity Mobile services ,Sim cards or devices .

Recently,I discovered that an agent secretly added an Xfinity Mobile line with an iPhone XR to my account under my name “Pha” without my consent .I have been wrongfully charged over $40 every month for a phone and sevice I don’t own.

I talk to an online agent today who managed to stop future billing but they refused to refund the money stolen from my account in previous months months,claiming they lack the authority .Since this is an identity fraud issue caused by Xfinity agent ,I demand a supervisor or a higher -level support team review my account billing history ,cancel this mobile line permanently and issue a FULL refund for all the months I was wrongfully charged .Thank you.
