One of our best customers moved in with her boyfriend and her daughter moved into her old house. We haven't kept much of any contact with the original lady, but she still sends the check when we send a bill to her original house. The question is, she had some limbs fall in the recent ice storm here, and her daughter hasn't answered our calls at all, so should we do the work and bill her since there never has been much contact anyways, or leave it be. If we leave it though, once spring comes around she will want it picked up when we could dump it at our city limp dropoff for free. Please give us some ideas.
