I have been receiving several phone calls from someone claiming affiliation with a Christian military fellowship organization. He knows our names discloses that he retrieved them from one of the organization's member directories. However, the caller talks very quickly and I cannot understand most of the conversation. The caller is impatient and states something about an urgent matter. The caller wants either (1) for him to call us back or send us an email, or (2) for us to call him or send send him an email. The calls have occurred between 2-4 am. 6-8 am, and 8 pm. Our CallerID displays these calls as "International" from numbers 2347040024273 and 2348038165090 or as "Not Available". The caller does not leave messages on the answering machine. I think that these may have emanated from Nigeria (country code 234). I am dubious about the legitimacy of the caller's affiliation with this organization when these calls occurred at strange times.
