This is a scam. Do not answer this call. If you do, the automated caller verifies your phone number by asking you if you can hear "him" ok. Do not verbally answer as this will verify your phone an active phone number.

I got the same message, a robot calling asking a question. Normally I don't answer a call I don't recognize, but I tried to refill a prescription earlier in the day and thought it might be the pharmacy calling me. Nope, it was this scam. The robot identifies himself as the customer service department and asked if I was the owner of the phone. I asked who are you with before realizing it was a robot and not a human. The robot responded "great let me tell you about an exciting offer..." I hung up and didn't hear any more.
Don't answer, started babbling on about how I won a trip and wouldn't stop talking when I asked a question. Probably automated. Added them to blocked list.
