Unsafe number. Caller represents he is Mr. Paul Williams and my elderly father, (in Florida) and he is a Publishing Clearing House winner. They are targeting the elderly, identify my father's address and state they have a delivery for him. He told me he was calling from Florida in spite of the fact I told him Publisher's Clearing House is located in New York. He told me I was mistaken but left me his number and told me it was a Florida number.  I checked the number and it is a Nebraska exchange. I called him back and asked him why he told me it was a Florida number and he said f__k  you and hung up.
