The same thing happened to me over 3/1/2024-3/2/2024. According to the daily breakdown, I used over 1TB on the 1st and 500gb on the 2nd. Here’s the kicker - our family was on vacation so we weren’t even home to use the WiFi. The customer support team is rude, dismissive, and incompetent. They had me convinced our router got hacked and so I spent the better part of the weekend factory resetting my router, changing all my passwords, scanning devices for malware, and contacting our banks to report potential fraud. Now after reading this I’m realizing my original suspicion that Cox is miscalculating our data usage is correct.
They’re either doing it by accident and choosing to turn a blind eye to a bug or they are committing fraud. Class action lawsuit?!?!!!!
