Burying internet line

I had my internet line installed in early April and had it buried May 4th. The landscapes working around my new build home unearthed the conduit with the internet line due to the Xfinity contractor not burying the line deep enough. Not the landscaper's fault, the line was literally buried just INCHES beneath the ground surface.

I had a new line installed May 8th but it is still above ground. The builders will be doing their final grading soon and will be putting down grass soon as well. I would like to have the line buried, at a proper depth, before more work is to begin.

Who can I contact about getting a person to bury my line out to my home sooner? I know there is a process, but I feel like since it was improperly buried the first time that someone should be sent out sooner to fix this situation.
