Cable left laying across driveway and yard.

You have to call DIRECTV (number in my greeting below) and tell them to get another technician out to bury the cable and poor job done by the previous technician. All cable should be buried and not EVER exposed, this is a poor and unprofessional job. In fact, see if you can get a free visit from a technician. 

From what I have heard, is this a pole mount, roof mount, or sled (non-penetrating) mount?

Either call or chat with customer service, they should be able to send someone out to fix this if it is left laying over your driveway or in your grass running the cable over with your vehicle or lawnmower will just do damage to it and it will need to be replaced again!  If it was me and I was home I would have voiced my complaint before they left!

I spent over an hour with customer “service” yesterday.  The girl was nice and seemed to want to help but finally gave up and said she would have someone call me.  Of course i have not heard back.  I will try the number in your sig though.  Thanks.
