They are debt collectors. I have a new business and I immediately started getting daily calls from this number. I called them back and they were looking for the previous owner of my phone number. They supposedly removed my number from their system. We'll see...
I think it's debt collection, but I don't owe anyone money. When I ask what it's about they won't tell me unless I give them my social security number. Not going to happen. Then they say something hateful and hang up.
