This is a pure scam. They try to get you to pay off, at a reduced rate, a made up debt. If you pay them anything, you are just throwing your money away. Nothing goes toward any debt. Just into the scam artists pocket and if you give them a credit card, they will clean it out.
This is a collection company, but they were courteous enough to ask if the last 4 digits of the SS# was mine.
I said no since they were not and they said thank you and hung up. I knew they weren't mine since I have no debts.
Called, left no message. But the machine got an message of air, meaning a robocall. BLOCKED. Obviously by all these posts it's a spamming debt collector having their computer make calls and see who answers.,
