Last year Dish installed a new dish and feed line for Eastern arc in my yard replacing two dishes I had. I paid $50.00 to have the cables buried. About 40-50 ft run. The person came out, took a shovel, skimmed back the sod about 2 inches deep, placed the wire and flipped the sod back over and stomped it down! Now I see orange cable coming up in several places in the yard which will eventually get cut by my mower. Will dish fix this for me free? Also, doesn't the NEC say low voltage wires have to be buried a certain depth? is Dish required to do this. I had assumed they would bring a trencher and had even gone to the trouble of locating several pipes and wires for them.that were 12 inches deep or so.
