Guys keep calling me asking if I have property for sale. Its getting very obnoxious. I don't know how they got my number and have repeatedly requested that they stop.

numerous calls from this number.

Woman claiming to be from Dell tried to confirm a contact name in order to deliver numerous packages.  When it turned out that person didn't exist, she decided to do more research and call back.  Dell (or whomever) phones continuously, asking to speak with various IT managers, and they're all solicitations -- most representatives have accents and are obviously working from boiler rooms (which didn't apply here, however).
