Did not receive a call from this number, however it was listed as the contact info for "Guy R Gunn" for a rental property I found on craigslist. The property was listed for $600/mo. I then saw the property listed on reputable sites such as trulia, zillow, and realtor.com and it was for $900/mo and listed by an actual real estate company. In an email he stated he worked for the united nations and would be out of the country for several years and decided to rent out his home since he was unable to sell it This is his website: 'http://www.un.org/en/index/html'.
This was surely a scam, and I did not respond back to the listing.
