terrible equipment

The last four week have been nothing but aggravation with our Home Security system.  What makes it even more annoying is that I pay over $300 for all xfinity services, $40 alone for the Home and the video recording.  The indoor cameras are dying. They are a bit older. I'm more than willing to purchase new but I keep getting sent thru these annoying trouble shooting steps that result in getting some discontinued customer equipment sent to me. These old pieces of equipment don't work. They were returned to Comcast for a reason. They look rewrapped and sent out to some unwitting customer who experiences nothing but frustration and aggravation. I experienced this with the touchscreen. It was replaced twice in the same week. It's a good thing I wasn't planning on going out of my home for a few days. Two used touchscreens were installed before I got something that worked. Then with that newer touchscreen the older cameras are not cooperating. The Xcam 1 started looking like snow was falling in my family room, then it just turned to a green haze.  I was sent an Xcam 2 and the technician made a big deal, "my camera is being upgraded!" Upgraded with something not working.  Several phone calls later I'm getting another replacement. I nicely asked that it not be a used camera and that it would work. I was told I get whatever is available.  Please remember I already said I'd buy new, but nope, I'm getting another camera mailed to me in three to five days only to go thru this exercise in frustration.  Somewhere in all that technical support, the tech had me delete the malfunctioning camera that already existed in my family room.  Guess what? I got no working camera looking at my front windows and a gun cabinet and the front door. You bet I'm annoyed.  I've read so many posts and wonder what drives loyal customers to tell Xfinity to take their equipment for a hike.  Now I know.
