Agreed. One "Tier 2" tech even offered to convince me why I was wrong to be so frustrated with and mad at COX's shoddy email service support. His reason: "We don't charge you for email service; it's free." Then he tried to describe why COX email wasn't broken and that the issues were likely with email clients. This after I told him that I'm a computer professional with 50+ years experience designing both software and hardware for large scale systems - including edge of the art networking. what can one say or do after such demonstration of misplaced bravado and rank incompetence?
I will continue using COX as an ISP but am evaluating Outlook.com (for fee) and Gmail. Sic transit Gloria, COX. Sleep with both eyes open, for either Amazon, Google or Microsoft will consume your business.
