That is Very common ...Tell me about it. The last two times my Hispanic neighbors cut through the coax in the ground for my internet cables I had the Spectrum Cable people come out and lay more coax and he would do that part but not dig the trench. He said someone else would come by in the week and do the trench. I ended up doing the trench myself both times because the neighbors couldn't mow their lot going to the canal behind our houses. The cable junction box is in their yard behind their house in the common utilities property. I didn't want to risk them cutting it again. It took a long time doing that in the heat of summer and we have clay soil that we call gumbo down here in southeast Texas. The crap sticks to your shovel and is hard to get out of the ground.
I have many years of laying cable to get a sub back in service and move on to the next ... we always have a buried contractor that comes along usually with in a few weeks (thier list piles up early from not being able to run the equipment in the winter, I know, down there its more than likely year round) any ways, most are happy to get back in service ... I have has customers ask if they could go ahead and bury the line, I always say Sure, we will still come out, but the person coming out will be happy when you already have it done ... and TY.
