Who called from 5204156068

Wen i called back they said an agent would speak to me and put me on hold then someone answered me and hung up.

my phone is my PERSONAL property!!!! My time is valuable to me!!!! I know nothing about what these calls are in regard to.
I insist that they stop

They most likely won't stop.   Invest in a call blocker and do NOT pick up on call numbers you do NOT recognize.

I constantly receive calls from this number and they hang up as soon as it is answered. I let it ring for a while (10 rings)and still upon pick up they hang up.

They keep calling my husband they don't  tell him where they calling from all they ask is for him to confirm He's date of birth and the last numbers of his Social Security but when he ask why?? they get mad and  hang up the phone
