Call History Not Working

Call history stopped working a week ago, .""We are currently experiencing technical difficulties...." then "Error while fetching call records"  Five days ago Tiffany told me to send an email to Cox which I did but they did not respond.  Four days ago I did a Chat and they said it was a nationwide problem and would be fixed by Friday - - yesterday.  Still not fixed.  This has been a recurring problem for 7 years.
