(update) I've gotten one call per day since I first reported this a couple days ago. Annoying that someone would waste their time doing this. I've gotten to the point where I just ignore it.
Received several phone calls from 408-189-0769. As the call appeared to originate in my local area code, I answered it, thinking it might be the appliance guy whose call I was expecting. The person knew my name and my husband's name. When I asked who was calling, they hung up.
In all, I've received three calls from them: 6/23/15, 7/13/15 and 7/18/15. BLOCKED.
