Another question about burying the Fios cable

I have seen many ask about this, and seem to get answers. I called a week ago about getting the cable buried, was told I'd be contacted by a local provider about getting the cable buried in 24 to 48 hours. 

It's a week later, no call, and the cable still isn't buried. How do we make this happen? 

Also, we have a lawn service. They will certainly run over it and cut it; who will be responsible?
