Need the cable to my house buried

Cable to our home was replaced once, and contractor damaged it when burying it, cutting off our service. Cable was replaced again in late June. You should have a record of when the cable was replaced - both times. Contractor came to bury cable June 30. He said internet would be down for 1/2 hour. My wife and I were both on work calls, so he said he would come back at another time. No one has come to bury the cable since June 30. We got a message on July 1 that the cable had been buried. I stated that issue in this forum on July 2. An Xfinity tech who had helped with the initial repair came out after that post, saw that the cable was not buried, and said he would make another request for burial. Here we are a month later - cable still above ground.
