Dispute Regarding Billing and Service Disconnection

My monthly home internet plan was supposed to be $30 per month, but I received a bill for $154. After spending a long time on multiple calls with Xfinity support, no one was able to explain why.

Without any notification, my service was disconnected, and then, after some time, it was reactivated for a few days without my permission resulting in an additional $100 charge. Ten days later, the service was disconnected again without my knowledge.

I honestly don’t understand what is going on with Xfinity. I feel frustrated and taken advantage of.
