MAC OS Sierra and cox security suite

I'v been trying to download the cox security suite since the 10th when I got the virus email from cox.  I called the cox security support number 4 times and have been told the site is having problems and try later to cox security suite is not comparable with MAC OS Sierra.  I called MacAfee and they say it is.  I called and asked for a conference call between MacAfee and cox support but they can't do that.

Any suggestions?
