A man named Mr. Dunbar called from an unknown number and asked you to call him back about a debt that was owed at 1-800-530-4180. Said he was calling to collect a debt. Very aggressive. Would never say who the money was owed too, would not agree to mail anything, and increasingly got aggressive when I wouldn’t pay. We know we owe nothing and he could never say why we owe money. Very clear that he’s someone who prays on the weak by being aggressive in order to get them to pay a "debt."
