(520) 325 in Tucson, AZ

I am on the no call list and they keep calling but no one says anything!

I received a call this morning from this number at 10:34 a.m. The person would not say who he was, only that this was a business call and he needed to speak with my deceased sister. She died on 2/8/2014, in a fire in her home. I do not need this. She lived near Seattle. I live in Vegas. After I told him she is deceased, I told the caller since he could not tell me what business he had with my sister, and would not tell me who he was, DO NOT CALL ME ANYMORE! I AM on the DO NOT CALL list. Is there no privacy? I should not get calls about my deceased sister! Fortunately, I have a phone where I can block the number, but it still rings, but the caller cannot reach me.
