On Sat Jan 16, 2010 around 7:30 am, I received 3 text message from this number, each with short message like "hi", "U there", "[email protected][email protected]" Then I received 4 calls from this number between 7:30am to 8:00am.  When I answered the phone, it's silet. If anyone else has received similar harassment like this. Please post here. Thanks
