Billing me for 2 phones I never had

I have THREE phones on my account, but they are billing me for FIVE!!! People at the Xfinity store kept telling us to come back so that a particular person could fix the problem. After repeated trips to the Xfinity store, they just told me that they can’t change the current billing cycle information. Never mind that it includes TWO extra phones that I never had. Then they told me to call Xfinity customer service at *611 which got me an AI robot that was infuriatingly persistent in ignoring my requests to speak to a real person. After about 15 minutes I was finally able to get the AI robot to stop. Now I’m on hold for who knows how long until I might perhaps get to talk to a real person who might perhaps fix the mistake that Xfinity made on my bill. If the point is to waste as much of my time as possible and convince me to find another phone company, then Xfinity has succeeded
