At XXXX, I received a call from Hatfield Portfolio Group. ( XXXX important because I 'm a shift worker and was sleeping ). When I asked what kind of business they were, they were vague and avoided answering and immediately started in with a list of names ( all with common last name, mine ), to see if I knew any of them. When I pointed out it was XXXX, he stated it was XXXX where he was. When I pointed out he was fishing for information, he hung up.
