DOCSIS 3.1 Upgrade Scam

I upgraded to DOCSIS 3.1 and Gigablast, and, instead of getting better, my connection is so slow I am getting kicked from online video games, and videos I upload, do not complete because of disconnects during upload. Cox please fix your lines/software. This has been happening for 11 years. Your technicians are incompetent and arrogant so I refuse to have them in my home ever again.
