Cable not buried for over a month

Cable is running across yard and has not been buried. This cable was laid at the end of August. Multiple tickets issued, but not resolved. Cannot mow the yard. Do not have any success with the local  sub contractors who do not answer their phone or return calls. Multiple calls to Comcast directly. After 34 years of being a customer, I am extremely annoyed. What does a customer have to do to get action???
