Internet Stops Working When Cold

Live in Indiana. It has just became cold. My internet has been going out whenever it becomes cold outside and comes back on when it is slightly above freezing. I'm getting frustrated, because I can't even get this complaint in front of someone until a technician comes out. And when he comes out he will probably have to try 10 other steps before getting to the actual problem, which I assume is the cable line running from the pole to my house. My wife and I need internet for our jobs and I hope Xfinity was more responsive to issues.
