The term investigative consumer report means a consumer report or portion thereof in which information on a consumers character, general reputation, personal characteristics, or mode of living is obtained through personal interviews with neighbors, friends, or associates of the consumer reported on or with others with whom he is acquainted or who may have knowledge concerning any such items of information. However, such information shall not include specific factual information on a consumers credit record obtained directly from a creditor of the consumer or from a consumer reporting agency when such information was obtained directly from a creditor of the consumer or from the consumer. 

I would like to know who did they talk to. 
How did they complete this investigation.
