Caller ( Ph # XXXX ) claimed to be with Arcadia Recovery Bureau, asked for me by name, then asked for my birthdate as a verification. Caller refused to disclose the nature of the call unless I furnished her w/ my birthdate. I terminated the call. I have no knowledge of the agency named, but it 's evidently a collection agency. I 've no knowledge of any debts that would have been given to such an agency.
