If it's a line that runs between two pedestals, then it is not a drop. It is a temporary mainline. Neither tech nor third-party contractors would bury that line, it would be done by the construction department. It's not unusual for it to take months for those lines to be buried; weather, engineering studies, permits etc all take time. There is nothing you can do but wait for Comcast to fix it.
Hi RJacksonGa -- I can help with that line. nerdburg is correct about what kind of line this most likely is and what it takes to have it taken care of. I can get in contact with our construction department to get a status on it. Please send me a PM with where this line is located and I'll work with construction to have it taken care of.
