Xfinity Tech Seems to Have Installed Service Incorrectly (no ground wire)

Last August I had Xfinity service installed at my home, but the service was installed in a strange way. The cable line was run from the utility pole directly into my home instead of first being attached to a box on the side of my house as is typically done. A coax outlet wasn't even installed in my house, instead the technician just drilled a hole in the wall, pushed the cable through it, and attached the cable to my modem.  At first I didn't mid this because my internet speeds are normal. Recently however, after inspecting the wiring, I realized that the cable line going to my home is not grounded. I believe that this goes against code and puts my equipment at risk for electrical damage. If any Xfinity employees on this forum could help me set up a technician appointment to fix this I would greatly appreciate it.

Thanks!

Edit: An Xfinity technician came to my house today and properly grounded the connection. As I suspected, the original technician had installed my service incorrectly. If anyone reading this has had problems with their installation, I recommend that you contact Xfinity support using the chat feature on the forum. The representative who responded understood my problem and was able to quickly make a technician appointment for me.
