Claimed they were from some sort of credit consolidation company. They immediately got suspicious when I requested information about the company and where they were located. Caller identified himself as Brian and said he was calling from Manhattan. When I asked for the address he hung up. So far as I know Manhattan is not in area code 608 (Wisconsin).
