I too was getting called by this number frequently. I finally got the call on the 3rd ring before they hung up. They asked to speak to Harry. I told them Harry passed away in June (truth). He apologized, I asked who was calling & he politely apologized for my loss, gave his name and company and said he would take "Harry's" name off the calling list. FYI, one method to get them to quit calling.
Constant calls, almost daily to our land line in Grand Blanc, MI and they usually hang up before the machine answers but not always. I'm blocking the number from our line too.
