Unburied cable in my back yard

Weeks ago comcast line techs had to replace a cable from one node to another and that cable crossed under by yard.  I talked to the techs that day the assured me that it will be buried fast and it hasn't.  Even though this will affect me right now if the cable is not buried this coming week I will remove the liability from my back yard if Xfinity does not bury the cable.   I already have talked with a sales rep at Ezze Fiber about replacing Comcast.
