Internet Issues - Consistent Lost Packets North Phoenix, Arizona

I'm now being told by Cox's Executive Support Team that this issue will no longer be investigated and is being classified as acceptable as a "Best Effort" consumer service.  I was also questioned about posts to multiple social media organizations, highlighting the poor performance of Cox's network in my part of Phoenix. 

Repeated interruptions of service with 5-30% packet loss during peak times is wholly unacceptable and would not fall under what any consumer would classify as "Best Effort" service.
