Screen saver mode

After doing a dance with Xfinity as to why my TV wasn't working I finally replaced the DVR as per their instructions. After the new DVR was plugged in I still could not get cable even after unplugging, plugging, checking doing everything and anything possible to make it reboot.  They sent out a service person who actually made two phone calls and then I had cable TV then Xfinity turned around and charged me for the service call.  So now my new DVR is doing exactly that, putting itself into screen saver mode which I hate.  I like my TV on for when I'm not here so that it looks like someone is here, for when I am home but may not be right in front of the TV (like when I am doing housework) and I leave it on for my animals as well.   There are many reasons I'm unhappy with Xfinity and this is just top the top of the iceberg.  It would appear that my old DVR was not the problem and it didn't have the feature where it went into screensaver mode plus I liked the old remote control box better because it had bigger buttons.   I'm really ticked off.  I talked to a total of 3 representatives for billing who told me that I got a refund for the service call when in fact the last person I talked to actually was the only one who was able to take care of it.  The last representative also said there was no record of my conversations with the previous 2 reps.  I wish there was other cable companies to pick from because with Xfinity having a monopoly in my area they don't care about customer service or anything related to their service.
