I just spent an hour (at least) with an xfinity chat associate trying to get my old iphone removed from our list of devices. I purchased an unlocked new iphone and took it to the xfinity store to activate it. No problems there, except that they didn't remove the old one. This person on chat kept telling me that they couldn't delete the old phone and that we needed to have three lines instead of two. I just about lost my cool after asking them nicely over and over to take the phone off our list. What the heck!!??
