AMBULANCE CHASERS!!
Called after a car accident from (no company name) the "accident resource center" wanting to steer us to all the help etc we are entitled to etc etc.

As another person stated, Ambulance Chaser! They harvest numbers from accident reports and call you with a high pressure pitch to set you up with an appointment for chiropractic service. They call repeatedly and from several different numbers. A call back to them, the operator identifies their company as National Referral Agency
