Vision Security GE auth rep Repair panel , authorized , GE , Enter home, Internet

While at home a representative of "GE" came to my door. He explained that there were break ins in the area recently and that they believe a faulty panel may not be reporting accurately. He showed me a picture of my panel on his iPad. They were authorized by GE to repair this panel and add a new chip to make sure it does not happen in the future when someone decides to cut my phone line (Indicating that is how the homes in the area were broken into). His lanyard around his neck said Vision Security (to which he never identified himself with)

I asked for ID and he said that if I go to a website, they will verify that he is an employee. He asked on multiple occasions to come in and start his work. I called ADT (my alarm company) to see if this guy was legit.
