My number is unlisted, I have DNC and have reported them several to that list. I wonder if they go to the same list and have a "search" device within their corporation to harass and bug people any hour of the day or night. At least when I didn't answer the phone, the answering machine picked up and some guy on the other end stated... "as you have not picked up our call, we WILL call again!" Don't ya love it! I paid for my phone, I pay for my phone service, and I get these types of calls all of the time.
