this number has been calling me everyday for the past 2 weeks. i didn't answer because i didn't recognize the number. today, i finally answered and there was an automated response that said something like "hi, i'm so glad you answered. i have an important message for you. please call me back at this number".  so i called back. someone said "hi, this is so-and-so, can you please hold for a minute?" I didn't hold, but now I know that it's a scam and the number is blocked. thank you vissy!
