Ever since I switched to gigablast this past Jan, my data usage has jumped from 700gb a month to 950+gb. I haven’t done anything different, in fact I have been using the internet a lot less since the last 2 months. I even disconnected devices that have been connected in my house for years. I also noticed many other people are having issues with high data usage as of the last 3 months. I am already past the point of being annoyed with cox and if this doesn’t get resolved very soon, I am going to switch providers.
