Pixelation on all tv channels

@user_8d0cc6 Hi there, thank you for taking the time to reach out for assistance. My sincere apologies for the delay in response, but I am happy to hear you were able to reach a phone agent and take some steps towards a resolution. Can I ask when your tech is scheduled to come out, so I can follow up with you then to see how things went?

Hey, @user_8d0cc6! How did the appointment go? Were we able to address those pixelation issues for you?

Hello, the tech came today and found one loose coax fitting behind the wall plate. The tech decided to check and replace the other wall coax fittings as well so that all rooms would have solid connections to rule out any inside home issue. Then the tech checked the line connection from the green street box that goes over to the Xfinity box on the building. That line was getting some errors so the tech ran a temporary coax line from the green street box to the building box until they can come and lay a new outside line. 
May I ask what the Xfinity policy is regarding billing so I know what to expect?  I would assume I would be paying for the inside work (the tech changing the coax connectors) but my understanding is that outside work (replacing the bad line) would not be charged to me?   Thank you.
