My cox email is not working.

A month later an my email recently stopped.  I, however am a Cox customer with a cox.net email from back in 2003.  For the past week or so, I only get emails downloaded from cox every few hours at best.  Using Outlook 2013 on my PC.  (At the bottom of the Outlook window on my PC the blue bar that says "Connected" on the right side also says on the left side "Filter Applied."  What's that about?)  Anyway yesterday and tonight, trying to watch The Great Course Plus (streaming service on my ROKU TV from The Teaching Channel) I got a notification that they changed their login procedure and I needed to set a new password.  The site said I would get a instruction link by email for setting up a new P/W.  No email received yesterday or today!  Logged in on my PC and could not get to my account.  Called tonight and after waiting 30+ minutes was told they had a problem sending emails through Cox.net, but they "were working on it."  Sounds like a Cox Problem to me.  This just, if anybody GIS. Cox truly **!
