Unburied cable issues

I recently had a new cable buried and the team who came out to bury it hit gravel and left several feet of the coaxial cable exposed and just piled the gravel in top of it.  I reached out to the cable technician who updated my equipment indoors and he escalated the issue to his boss and in turn got with the management of the dig contractors.  A ticket was opened and within hours tge ticket was closed without explanation.   I have yet again reached out to Comcasrmt and a new ticket was to have been opened again.  Sick of this run around. This situation causes a major safety issue for me running my  tractor mower and for my lawn service
