This is American InterContinental Univ. Online.  The caller ID showed the number 910-779-4791 with the name of 'CCI'.  They left a voicemail saying "it is very important that I return this call urgently".  The message said to call 888-700-2510.
I called back and a lady asked me "which one of their schools do I attend".  I told her "none... I have my BSBA from a local university founded in 1906 and never took an online class in my life".
She then hung up.
