They send emails asking you to purchase leads from conventions, in my case they were "supposedly" from the 2018 Dental Convention. I told them I would pay $150.00 and they immediately sent me an invoice. I checked out the URL's and neither work so I said I no longer wanted to move forward and got an email back saying "your a dumb F anyway"!!! BE VERY CAREFUL, I WOULDNT EVEN OPEN ANY DOCUMENTS FROM THESE PEOPLE.
