I want to know what is causing my usage. We had in important football draft coming up so we would just use the computer very little to save for that day. The other day I was at 8.6 and then that evening I was over 12 GB. I only checked the computer a few times that day, my husband didn't use it, nothing is linked to our system. No phones, no TV or anything. All we do is usually brows the web and check emails. We had this problem when first started with program last Nov. we called our service person who installed it several time with no response. The extra usage stopped after the 4th call to him. I don't know if it was a coincidence or not. But it has started again right when we need the internet for something important. I need to know what happened and why.
