Exposed wiring hazard complaint - pedestal

This is my third attempt to request that wiring be covered up under the pedestal box near our sidewalk as it creates a safety and property hazard.  Work has been done in the last six months in our area by Xfinity or one of their subcontractors.  As you can see in the pictures, there is a open trench under the box with wires exposed.  Our first attempt to request it be fixed or filled was by phone to Xfinity.  They came out, and we were told that they planned to install a larger box that would cover up the hole and wires.  A few months went by with no action, so we contacted Xfinity a second time by submitting an electronic ticket for the hazard.  Xfinity visited our house a second time in early September and said it looked like 'no big deal' and that they didn't think or intend to do anything about it.   

We have many young children in our neighborhood who use the sidewalk.  This will be the third time we have made Xfinity aware of this situation.  We do not want a child to get hurt by this "no big deal".  All we want is for this to get fixed, which does not seem like too much to ask.
