I couldn't disagree with you more. I didn't ask them to call me, I have zero known medical conditions, and I'm not on any drugs, prescription or otherwise. Furthermore, I'm not expecting any bill collectors to call because I'm not past due on anything. Now, explain again to me what it is you--errr--I mean, they, are calling about.
They are not Selling anything people. They are not bill collectors. Stop running scared.
They are a healthcare consulting firm, and if they have your number, it means you have some sort of medical issue and you have seeked assistance in some form. They are the ones that can assist you with getting help. If they are calling you, it is you that "NEED" them and it is their job to help you. Not everyone calling you that you don't know is a Bill Collector or Sales Person.
