I've monitored my usage for months. I usually average between 25-30 GB per month prior to September. In September, something changed. Beginning mid-Sept, my usage jumped over 100 GB in one day. I checked my usage on Dec 10, 2015 and I had used 7 GB for the first 10 days. That evening I also noticed that there was internet interruption in my area. I was able to check email and local news. Looked at nothing else. On Dec 11th, I checked my usage and I had used 150 GB since the previous day. I have everything turned off at night. I'm not doing any iCloud backup on any devices and I checked my router to see if anyone else might be connected and it was only my devices. There is no way I used 150 GB in one night from 7:00 - 10:00 pm. Two days later, I've used another 80 GB and again, I've only checked email, local news, and Amazon. I very seldom stream videos. I called and they told me to change my firewall password, which I had already done. They said maybe someone in the house is using more. My wife is the only other person and she has not. They said that maybe it was a virus. I told them I was using an iPad only. They were absolutely no help at all. They said I had 3 courtesy months, so what was the problem. I told them I did not want to use the courtesy months if the usage is not my fault. We haven't changed any online practices, yet my data usage goes up 10-fold over the last 3 months. Some thing is wrong and Comcast offers no help at all resolving the problem. If it is not fixed soon, I'm going to change providers.
