CNAC Harassing people of References Columbus Ohio

 This company has begun to harass people that i have put down as references when i financed a vehicle from JDByrider.I have had this vehicle over a year,and i was a few days late on my payment for the very first time.I called them to make my payment and they began to talk to me like they were punishing me.I asked them several times were they going to take my payment and they never answered me,so i hung the telephone up.Now they are harassing these people i used as a reference by calling and calling them.This harassment need to stop immediately.
