I don't use it, but I think the use of electric poultry netting is to keep predators out, not keep the chickens in. They will stay in even if you just have regular chicken wire. (Keep in mind, though, that that's the only thing chicken wire is good for. It won't keep anything from getting to your birds). Your neighbor has shown great patience in only speaking to you twice about the chickens in the garden and not taking further action. As far as, "the chickens love going into the woods".... You are the human. That means you're in charge. It's your job to keep them safe. It's kind of like with the kids. They may want or like something, but as the parent, you are responsible for keeping them safe and out of trouble. (At least until they're old enough to know better, then they need to face the consequences for their bad decisions. Chickens don't understand consequences, so you have to think for them always)
