I received several phone calls from an unknown caller whose phone number appeared as unknown on my caller ID.  I answered the phone and the person ask to speak with Gloria.  I advised the person that Gloria does not live at this phone number.  He immediately asked who I was and I did not respond.  I immediately hung up the phone.  The person preceded to call back using the number of 234-803-9451.  He asked the same questions previously and I politely hung up the phone.  This person claims to be from Nigeria and has called around 6:00 a.m. weekdays and also Saturday around Noon and 2:16 pm on 5/30/09.
