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.
