Phone Service Down For a Week

I have had no Cox phone service for almost a week.  I was told by support to "unplug your phone from the modem then plug back in after 20 minutes".  This resulted in no change.  I am unable to access phone tools.  The support solution was that they would send a technician out but were unable to confirm if this would be charged to me or covered by Cox.  Nothing in my set up changed.  Nothing was moved.  Everything is exactly like it was when I configured the service. I have no dial tone at all. Does anyone have any solutions for this problem?
