There's actually a decent chance it's a real company. I once got a call for insurance that I was sure was a scam, but after playing them along for several calls, I found out it was a legit company. I talked to their CEO, who was very nice, found out their company name, and then explained to him that I could sue him for several thousand dollars. He apologized, said it was an outside firm that they had been working with, and said they had stopped working with that company because of complaints. I didn't sue them.
