Collection Concepts Inc

IT IS A SHAME THAT COLLECTION CONCEPTS CALL THEMSELVES A REAL "BUSINESS". THIS HAS TO BE THE WORST CUSTOMER SERVICE I HAVE EVER SEEN! THIS STAFF HUNG UP ON ME BECAUSE APPARENTLY I ASKED TOO MANY QUESTIONS REGARDING HOW THEY ARE PROCESSING MY BILLING. DO NOT, I REPEAT DO NOT, USE THIS COLLECTION AGENCY! THEY HAD OUR ACCOUNTS FOR 4 YEARS, AND I HAVE YET TO SEE ANY MONEY RETURN AT ALL!!!!!
