If you go look at reports you will see that they try to ask if you have a blood clot because you can get "compensation". The weird thing about this scam is that they want you to say the word "yes". If you go look at a few detailed reports you will see that they try VERY hard to get you to say the word "yes" and if you don't do it after a while then they will hang up. The question is.. what are they doing with it. I find this scam really weird.
If the number doesn't work today then who knows, maybe they don't work on the weekends. I know someone who called them the other day.
