Wrong Caller ID

I've had Xfinity Mobile for over a year now and it has always shown the wrong Caller ID for me. I have called Xfinity numerous times and was always told that Xfinity uses the Verizon network and that Xfinity would contact Verizon to correct the problem. But the problem has yet to be corrected. Now I called and said that after a year of this perhaps Xfinity should issue me some sort of refund. This time I was told that the service does not include Caller ID! It's really wrong that customers are not told this when purchasing the service. So for all intents and purposes I remain a real estate company when I call someone! Well, I suppose that is better than being identified as a funeral home, lol. At this point I am mulling over cancelling the service although coverage in the Boston, MA area is good and the price is very reasonable. I've seen on this forum that other folks have the same problem. It's pretty off the wall.
