Got the calls too. I called back one time, and decided not to talk for a little bit. After a while I got redirected. Got new dial tones and a gentleman pickup. They are selling diet/health products, but strangely, the gentleman I talked to said he was not aware of the call made out to my number. Is it possible somebody is trying to illegally use their company's number to call people? If that's the case, I hope whoever did it will get caught.

i get those calls too. i hate them.

Repeatedly calling and stating they have obtained very important health-related information. They just instruct to call the number back.
