Have received 3 calls in the last 24 hours from this number. The first 2 calls were within 20 minutes of each other; I answered and immediately disconnected. The third call I answered but didn't speak; after about 15 seconds of silence the caller hung up. Not sure what they want but I do know that as a general rule phone companies don't give out numbers with a 555 prefix (that's why movies and TV shows can use "555-####" numbers without fear that they are giving out a live number that may actually belong to someone). Don't know what these guys are selling or scamming but I'm not interested.
