Why send e-mail offering a hot new feature/service that doesn't actually exist? I received e-mail about the new "Advanced Security on the go for Mobile." All I had to do is install the XFinity app, go to Advanced Security, and I would see the feature, except it isn't there. Typical. The quality of service from XFinity is dropping like a lead weight. We pay them so much money every month, and then they can't understand why they have the churn they do. This is why.
