This number called me so I called it back after being on the line with it for all of 30 seconds of silence. The machine prompted it being \"Xfinity\" and since I don\'t have an Xfinity account I selected the representative option (0) and waited on hold for one. After informing the man on the line that I don\'t have an account and to ensure I don\'t get called back, he put me on hold and then hung up. On the second call to them, I got the same man on the line and I made the same request, to which he rapidly said \"Shut the ***k up, shut the ***k up right now!\" before hanging up. On the third call back he hung up the moment he recognized it was me calling once again.
