Formerly known as Newtown & Assoc. now Coface North America. its a collection agency that uses intimidating tactics. Linda Blair is one of the collectors who tries to be a bully telling you how she will shut down your business in a split second... it's not that easy lady.
Even after you tell them you are not who they are looking for (they were looking for a man and I'm a woman) they threaten to garnish your wages. Rude mean people - don't let them bully you. Or better yet - ask them to hold on - and tie-up their time. Everytime they call you tell them you are getting the person they need and just lay the phone down. That way they are not annoying you and they can't call someone else and annoy them.
