I had the same problem when I bought my place. I took care of it with some personal risk. I am not suggesting that you take the same path, but I felt that I did not work for what I had to have it stolen. Be sure that you can back up whatever you do. I made it clear in person that I was the owner and they were not welcome to trespass. If you are not willing to take these personal risks, then you will likely deal with your present situation for a along time. I cannot emphasize enough that this is dangerous business and I am not recommending it to anyone else.
