It would seem that who ever it is has decide to spread their wings. I am in the United Kingdom and I got a call from this number at 10.56 am this morning. My answer machine cut in and recorded the sound of an office, but no person leaving a message.
Same as BHW but have called three of four days in a row and hang up before the answering machine kicks in - don't know no Jess or Bill and don't intend to "get to know them"
