Missing DVR recordings

Sorry to tell you this issue has been going on ever since Xfinity began putting DVR recordings in the cloud.  I have lost over 30 recordings over the past year.  It happens during the nightly "reboot" update.  Xfinity is well aware of this problem and is doing nothing about it.  I have dealt with several of their "executive care team" members and have had several tech guys out to the house.  I can tell you it is not your equipment and there is nothing you can do about it as they won't fix the problem which is at their back office.  Their engineers are aware but again nothing.  The only work around I have found to be effective is to disconnect your set top box from both cable and power every night.  It prevents the nightly software updates and you shouldn't miss any recordings the next day.  Of course this is a real pain.  You won't find anything in your DVR deleted file and none of their tech people can restore your missing recordings.  It has nothing to do with the amount of space you have remaining on your DVR.  Again this never happened before they started storage in the cloud and the storage capacity indicator on your box is also funky...yet another problem they won't address.  I real drag that we pay 10 bucks a month for terrible service.  Don't bother if you get a response from an xfinity employee saying they would like to look into this issue for you cause they can't do anything about it.  Oh and a final thought is the deleted recordings are selected at random and have nothing to do with how old they are.
