I haven't had the same thing happen to me but, if you have Sprint as a carrier in your area you can add a product that will not let an unidentified call through to your home. If the person insists on calling you they must record their name and you must give them permission to allow the call. I know it sounds extreme. But if you put it on your phone for a month at least you'll know who is calling and it will stop. Good luck. Curiousdee ps-I think it was developed to keep the telemarketers at bay.
