This one is hard to classify because they do a whole array of scams off this number, and it’s not Social Security. But they have done stuff like telling you your Medicare card will be deactivated if you don’t call them.
If you call the number and Press 1 you're told you're the 45th caller and you've won grocery vouchers.
It makes about 2 calls a day to one of my numbers. They get excited when Lenny picks up (old man bot), only to realize he has no credit card or bank account numbers to give them LOL.
I sent some robots after it to shut it down, but they'll pop back up probably later this evening or in the morning tomorrow.
