I just got a robo call from them, giving me three options: press one to schedule carpet cleaning, 2 to get more information and 9 to never be called back. I hit "1", and the voice on the line said "Do you want to schedule carpet cleaning?" I replied that I wanted to know who was calling me as I was on the 'do not call list'. They hung up on me. No internet reverse phone directory will give me their name for free.
This is a spoofed number. The business they mention in the prerecorded message doesn't exist. So either they're looking to scam you, or they're looking for live numbers to sell to other robocallers. Either way, they're the scum of the earth.
