Technicians don't know what packet loss is

I've had issues with cox multiple times throughout the past few years of service. Much of it just consists of getting severe packet loss which I've logged through multiple applications. Every time I have contacted the support lines, I've always been told the same things. Oh it must be your modem, please replace it. No it must be an issue with cabling in your home. I've replaced my modem and cabling multiple times to prove that it is not my equipment, which cox of course does not compensate. The tech support is only taught two things, how to reset a modem and to sell cox complete care which does nothing. When they obviously cannot fix the issue with either of these suggestions, they schedule a tech to come out. This is where it becomes even more ridiculous. I have months of logs show casing the packet loss that I've been experiencing yet not a single tech want's to know this information. And it comes down to one simple thing, every tech outside of a supervisor have all told me they have no idea what packet loss is. I've had to explain to them what it was and how it affects my service. They don't even know how to test for it. How is any of this acceptable? My service is degraded and when I try to inform cox of the issues I'm having, their decision is to send an incompetent tech who does not even understand the problem the customer is having.
