Keep getting a call from them. DO NOT ANSWER. If you do you will be redirected to a machine and be added to their list and then good luck because they wont stop calling you, EVER! I swear, theyve been trying to get a hold of me for 5 months because I answered they first time around. I do not know the motive but my clossest guess is that if you return the call at the number they ask you to, you might be charged astronomical prices per minute and end up with a huge phone bill. So just don't answer and if possible on your phone, block the number. I cant seem to block a number on iphone, smartphone my [***]. LOL
