XRE 03121

Long story ... updated main box.  Didn't work properly.  Service tech dispatched.  Yada yada ... on the 4th box.  That is finally working but small boxes can no longer get regular programming.  DVR works, streaming works.  Two more techs sent out.  Boxes upgraded to new wifi.  Things work for a day and then we get the above error code.  Boxes obviously work, link to comcast obviously works.  Seems to me that every evening when Comcast downloads updates we lose our channels.  Seems like somewhere in the process of upgrading and then downgrading something happened to our record.  This has been going on for over a month.  I can't begin to tell you how many phone calls to level one helpdesk and software refreshes have been done.  How do I (and money for services I am not getting) on this problem.
