Comcast needs to complete undergound cable installation

Hello, my fiber cable was installed May 22.  The conduit was installed two weeks later for underground installation; the underground conduit installers said that they could not work with the fiber cable and that an installer would have to do that.  I've reached out through chat, phone calls, visits to the local Xfinity office, and also stopped by the office where the Xfinity truck crews work out of.  Each person was helpful but they could not control what happens after we break off talking.  As it is, the cable is still on the top of the ground in a walk area where I have to mow regularly.  I'm concerned because I know that fiber cables are not as tough as the older underground installed cables.  We don't want to trip over the cable or to have it cut by the mower or a weed whacker.   The conduit already has some type of pull cord (or similar) ready for pulling the fiber through.  Cables leading up to my property have already been marked twice, and I think a third request is now in progress - not necessary since your team installed conduit after the first marking; I have left the marker flags up since I hope at some time someone will wonder about what is going on. Now, all that someone needs to do is to pull the cable (already there) through the conduit (already there), and remake the connection on one or both ends.  We are very totally satisfied with the signal that we are receiving.  No one had yet mentioned this board and I'm hoping that this works.  If you can help in any way, we would be very thankful!
