I can't pick up some of my channels - DirecTV

Theresa is about 6 or 7 channels that I can't pick up. And it may have something to do with my dish sitting on the ground and I have dogs and they may have moved it but I'm not sure. Can you tell me if this could be the problem. It's been on the ground for over and month well ever since it was installed, the man said he had to have a locate done before he could put it on and poll, and we haven't heard anything since then. I'm getting very disgusted with it.
