Collection agency

Did not leave message -  since I have absolutely no debts of any kind - not sure why they called my number

Said they were from Who's Who in Business.  She asked several questions concerning work and personality traits before offering two different types of memberships with their organization.  She was "pressed for time" when it came to wanting me to quickly choose which membership I wanted.  That's when I decided to end the call.  

The number always it's a non working number when you try to call back
I always ignore it

? DONT KNOW CALLER
