So I'm on the phone with Xfinity. Trying to get my bill down. And they know I'm a Verizon customer. And keep saying ........."just move your phone with Xfinity. There is no difference in your service at all. We have an agreement with Verizon. Just move your phone and save XXX $$$ a month. It's a no-brainer." There has to be a catch. Nothing is THAT good just by a click away. What is the deal with Verizon and Xfinity? Why would I want to move my phone service to Xfinity just to save $$$? I find it hard to believe there will no change in my alrady awesome Verizon service. Please advise.
