L.E.
I would call the phone company and tell them about it and see if there is anyway they can trace the calls or find out where they are calling from. Or at least find out what you legally have to do to have them trace the calls and get the origin of the numbers. In this day and age I can't imagine there is no way to find the number of who is calling even when they come up with no number. Also, I don't know if you have done this, but record the calls hand them over to the police and keep on the police. This is harassment and they should be able to do more than investigate. If anything they should be able to trace the calls or record them and find out where they are coming from. Also Let the business lady know that you are having some issues and to leave a message with her number and you can call her back so you don't have to answer the phone. You don't have to go into detail with the lady, just make her aware there is something going on and you are taking care of it and in the meantime that is how it will have to be. If it is kids, they will eventually get bored and things will get back to normal but if you keep answering and reacting to them they will keep on. Hope you get some relief soon.
