They called my phone but didn't leave a message. When I tried to call back (twice), I got a message on my phone saying the call could not be completed. According to a reverse search on whitepages.com, they're located somewhere between north 1st and 2nd streets in Harrisburg, PA. Go figure. You'd think if they were serious, they'd leave a message.
I thought credit agencies weren't allowed to call at certain hours and/or days like Sunday. It was an automated call asking for an unknown person but nobody to tell that to since it was a bot.
