"This is a Courtesy Notice from Comcast to let you know that you have reached 90% of your 300 GB monthly data plan for your XFINITY Internet Service. As of 11-10-2015, you have 29 GB remaining for this calendar month." Just started getting these notices. I'm not sure how to feel about this. Am I using too much data through YouTube and Netflix? Do I stop using YouTube/Netflix? Or pay the highway man his extortion?
