They prey on little kids playing video games (and curious adults) with a pop up asking  for name and number offering prizes.  Rule of thumb -- NEVER give a credit card number to an unknown caller no matter what they offer!  East fix, when they call, block the number in your contacts.  Kept blocking them.  I thought this was against FCC regulations, but I guess the bogus pop up gives them permission.

Calls non stop including nights and weekends. I never seem to get to the phone in time because they hang up as soon as I pick up the phone. It's infuriating.

i started to get calls from various numbers I did not recognize when I posted my resume online. Calls are not from recruiters, if so they would leave a message! Got a call from this number and they hung up!
