They called no message... I called back using Google and they were not happy with me :) They first refused to give me the name of the company. Kept saying they are a private business in IL... then he finally told me they were CCB. Still no idea who they are... he became very irate when I refused to give him my number and name. So, no idea what they want :)
Left a recorded message asking for a person unknown to me requesting that person call them immediately about a debt. Best guess is a Collection Agency.
