schedule a technician

We have two problems. 

1. We are experiencing periodic audio and video outages on cable channels (not streaming). The audio will go out and then come back or the audio will repeat several times (like a hiccup in the middle of the program) or both the audio and visual will go out.  It is most annoying.

2. We have one tv that seems to be in a permanent update loop yet the update never happens.  The TV doesn't receive any able programs.

We need a technician to come out and fix these issues. They have been ongoing for several months.
