I got a flier from RAD Investigations stating to call this number regarding someone we don't know.

I too received a flier from RAD and they say they cannot tell me over the phone what it concerns. They want my address but I'm not comfortable giving it because my husband works out of town weeks at a time. If you don't mind, can you tell me what they wanted from you? If its personal I apologize and I understand if you don't answer. Thanks for your time
