Unburied drop line unresolved for 3.5 years — need escalation

Hi — I need this escalated immediately. Xfinity has left an exposed/unburied drop line in my backyard for approximately 3½ years. Multiple prior requests/work orders have already been submitted and were apparently closed without the work ever being completed.
I am not looking to reopen or review old tickets. I need a new active drop-bury work order and escalation to the local field/construction team, with confirmation of the work-order number and an actual completion timeframe.
My next-door neighbor recently had the same issue and, after requesting escalation, Xfinity completed the burial within 48 hours. There is no reasonable explanation for my line to remain unburied after 3½ years.
