This one called today at 4:23pm EST while I was at work and I decided to answer it. It was a robocall and gave another number (I wish I would have written that down) to call back to discuss suspicious behavior with my SSN.
I called this number back instead to mess with them and they answer saying “Thank you for calling the social security admin dept”. It’s going to voicemail right now so I imagine they’re sleeping or something.
Enjoy
