excessive data use charges

My Wi-Fi router doesn't have a robust log monitor, so other than a basic byte count per day, it doesn't help identify the root cause. My complaint is now really Cox refusing to provide the logs they use to track and claim excessive traffic volume. They told me the logs "track destination, port and protocol to determine categorization", so I thought I was on to something. I can correlate IP address and protocol to a specific service myself, which is all I was asking for. They refused to provide the logs, indicating "privacy policy". When I advised the logs contained my own (nobody else's) information and privacy concerns weren't a valid reason, they didn't have a good answer and again advised me to change the Wi-Fi password on my router. At that point I just gave up on the call. 

Maybe I am being petty and making too much of the issue, but it shouldn't be this difficult to get specific details on the information they obviously capture and use to calculate overages. It seems like a "trust us, you really are using that much bandwidth, even if you haven't changed any usage behaviors or device types in the past 24 billing cycles, so just pay without question".

I just enabled my RAXE 300 traffic meter, my bill resets on midnight of the 15th, I am set to reset on that date, so NEXT month, I will be able to give you a good monthly,  since we have 5 more days, after today I can check daily accuracy and give you more info.
